There was a nice open space on the inside of the driver's side
fender. There were even pre-threaded holes available to bolt to,
so I made a bracket, bolted it in,
attached the control box to it, and made the required connections.
On the right I have mounted the activating cylinder to the brake
pedal and connected the pull cable to the floorboard. The black
tape is to prevent a tear in the
rubber mat from extending. All of this is out of sight at normal
viewing angles.
Towing
setup:
Even though the car came equipped for towing, there were several
things I needed to do. On the Tracker, there were two wide
openings in the area below the grill. The base plate connections
to the towbar, along with the connections for the safety cables were in
the upper opening and the electrical and braking connections were in
the lower. This made life easy, as there was plenty of room.
This car has only one such opening and I need to fit everything into it
in a manner that there is room for inserting the retaining pins into
the base plate and a method of connecting the safety cables along with
the electrical and braking connections. I attacked the problem
one item at a time.
First I looked at installing and removing the retaining pins.
These insert through part of the base plate and the removable towing
arms inside the grill slot and are locked in place with a spring
clip where they protrude through the other side. It is pretty
tricky holding the pins and getting them to insert into the hole.
I solved this by attaching a thin steel handle to the end of the pin
with a small hose clamp. This handle allows me to manuever the
pin
from the outside of the car and insert it into its hole. The clip
snaps into place using either a tool I made for the same purpose on the
Tracker, or using needle nose pliers. That solved this problem,
but still requires a fair amount of free space to do the
manipulating. You can see the silver retaining pin in the photo
below
at the very left opening of the grill, with the handle I added just
into the second opening. The loop of the retaining clip just
shows at the very left of the first opening.
The standard Roadmaster method of connecting the safety cables is to
either connect them to a plate bolted to the front of the removable
arms or to extension cables attached to a pair of tabs welded directly
to the base plate, again well behind the front of the lower grill
opening. Since I want the cables to protect against the greatest
number of possible failure points, I ruled out the "easy" front bolted
on plate approach. I machined a heavy steel extension and bolted
it to the supplied tab. This allows me to clip the safety cable
directly to the extension at the front of the grill opening. My
first approach was to extend only the tab on the passenger side, as I
figured I could clip the other cable directly to the under-bumper tow
loop which is on the driver's side. This loop can be seen in the
second photo below.
To mount the electrical connector, the breakaway switch, and the air
connection for the brakes, I mounted an aluminum plate directly to the
frame behind the bumper fascia. Most people just mount directly
to the flange of plastic on the fascia resulting in a very flimsy,
flexible mounting. I want sturdy, non-flexing mounting which this
plate provides. The photo below shows the installation which I
used on our first campout towing Suzi. It worked well, but . . .
This is the result of my first attempt at setting up the towing
system. The breakaway switch is shown in the towing position.
For normal driving, it swings to the side and stores under the
air connector. When I actually connected it to the motorhome,
I found that the safety cable did not reach the tow loop under the
bumper - I had not properly allowed for the towbar position
during towing. I added a couple of extender loops and all was
fine, but it was not ideal.
Our first time towing the car worked very well, but I was not
happy with the one safety cable clipping under the bumper, and I felt I
could do better. After returning home I did several drawings to
see if I could compress things to a size that allowed me to fit the
other safety cable bracket into the limited space and still allow
clearance where needed. I ended up with a scheme that actually
allowed about 3/4 of an inch more than the minimum I needed.
Without too much effort I made a bracket which mounted both the
air
fitting and the front of the breakaway switch, made a second cable
bracket, and re-drilled and tapped some holes in the mounting plate.
My final configuration is much cleaner and allows room for both safety
cable brackets along with the
needed clearance to install the locking pins and clearance to connect
the cables. The factory tow loop
seen under the bumper is no longer used.
Lights:
The car has two dome lights and a couple of map lights up front.
All of these were more of an orange glow than real, useful
illumination. I had several small LED lights left over from
updating the Volt which fit the map lights and the rear dome
light. These increased the output a great deal. I also had
a dome light consisting of a large array of LEDs - 36 total which I had
bought for practically nothing on Ebay for the Tracker, but never
used. It was the ideal size to graft onto the original light
fixture, so after some thinking and re-thinking I designed and 3D
printed a small adapter box which allowed me to take the LED array and
mount it on my existing dome light. This puts out a wonderful
amount of light and is a good addition.
The other area of the lighting I have improved is the headlights.
As received, the lenses of the headlights were just starting to
deteriorate into a foggy finish. They were still basically clear,
but showing a slight haze. I bought a Maguire restoring kit which
includes a very fine sandpaper disk (1000 grit) and an even finer one
(3000 grit) and a polishing pad, polish, and a coating to retain the
finish. After a session with my electric drill, a spray bottle of
water, some microfiber cloths, and some elbow grease, my headlights
look factory new.
The LED dome lights now provide bright, useful illumination. The
map lights (not shown) are equally bright.
After performing the various sanding and polishing steps, then adding a
protective coating, the headlights look factory new!
Backup camera
and radio replacement:
I am a huge fan of backup cameras! I have either added or
improved them on every car I have owned during the last 7 or 8
years. Suzi is no exception! Before our first trip, I
mounted a camera and ran the wires forward to the dash. This was
in preparation for changing the radio to one which could display the
camera image, but for now, I temporarily mounted a small monitor below
the radio area on the dash. This was really just a proof of
concept, and I was impressed with the results.
I had a hard time deciding where to mount the camera considering the
best viewing location, easiest wire runs, durability, etc. I
ended up mounting it on the
bumper below the spare tire. This gives a good view and avoided
having to route the wiring through the hinged rear door.
Before I talk about changing the radio let me give a quick
description of car radios. With a few exceptions, most car radios
fall into one of two size groups. A single DIN radio is about 2
inches
high by about 7 inches wide, and for many years was the primary size of
car radios. The other standard is a double DIN or 2 DIN radio
which is 4 inches high by 7 inches wide. Many cars today use 2
DIN radios with a large touch screen which shows all the radio
functions electronically as well as the backup camera images.
This is what I want to install in Suzi, but there is a problem:
While the basic opening in the dash structure is a full 2 DIN size, the
plastic decorative bezel is not. It has curved sides and corners
to the opening which will prevent a standard 2 DIN radio from
fitting. As a result, all the manufacturers of after market
radios state that only a single DIN radio will fit this car, and
therefore no one makes the required bracket that adapts a 2 DIN radio
to the dash mounting.
After removing the existing radio and checking all the measurements, I
decided to purchase a touch screen 2 DIN radio, make my own mounting
bracket, and cut out the opening of the bezel to fit. This is a
lot more work than the normal 1 to 2 hour installation time should
be. I did a lot of research of available radios and selected one
from Amazon.
The after market radio that a previous owner installed is a single DIN
radio with a couple of ugly filler
panels to fill out the almost 2 DIN opening
Making the mounting bracket turned into a much larger job than I had
anticipated. I went to the local scrap yard and found a nice
piece of galvanized steel, .040 thick for $2. I looked at several
methods of mounting a bracket to the side of the radio where the
mounting holes are and to the top where the dash mounts are and finally
decided that the most practical is a band around the radio - a box
without front or back. After trying to figure how to design
something I could then bend into shape and still have it fit, I
remembered that I have a portable spot welder which I have not used for
a very long time. I dusted it off, resized and refinished the
electrodes and tried it on a scrap of my metal. It did a superb
job. Now my job was much easier. I cut a strip of metal,
bent it into a box shape with overlapping ends and spot welded
it. I them made small tabs and spot welded them in the correct
locations. This involved a lot of measuring, but was easy to
accomplish. The box was a little wider than the radio and if I
shimmed the gap, the screw heads would extend wider than the dash
opening. I made a super-simple tool consisting of a washer, an
aluminum block with a depression machined into it and a pin for
alignment. Setting this up around each mounting hole and pressing
it in the vise gave me professional looking dimples. Now
everything fit and I could mount the radio in the dash.
The wiring harness was fairly simple. The radio came with a
harness with many colored wires. I purchased a harness that fit
the factory connector in the car and spliced its wires, color for color
to the radio harness. Now it was just plug and play. There
were several wires that I had to handle separately. Three wires
that link to the steering wheel controls, and the wire that senses the
backup lights to set the radio to backup camera mode had to be
connected individually, as the car harness did not include those
wires.
Making the mounting bracket was a LOT of work, but the results were
worth it.
The completed radio/bracket combination mounts into the dash cleanly
and solidly!
In the process of enlarging the opening in the plastic bezel, I
inadvertently destroyed two small plastic clips that allow it to snap
into the
dashboard. With my 3D printer coming to the rescue, I was able to
make two replacements as shown on the right - and they worked great!
The final installation looks like it was originally designed that way!
The radio I purchased for a reasonable amount is truly amazing. It has a very good sound and includes
screens for adjusting the equalizer settings and the speaker balance
settings. It includes full GPS navigation, which with the very
little I have used it seems much more intuitive than the one I
installed in the Tracker. It displays the backup camera image
well and it also includes Bluetooth connnections
for both hand free cell phone calls and wireless music from your cell
phone. It includes 2 USB inputs along with micro SD card and 3.5
mm
phone jack inputs, and it will play CDs and DVDs. If it holds up,
it cannot be beat. Time will tell.
