18 Cruise Control

 

On December 3, 2008, I bought an Audiovox CCS-100 cruise control unit which was being closed out by Checker Auto Parts. The price was $13.76, but since I was an employee, I got a 20% discount. The final tab was $11.86 including a 7.72% sales tax. Until last week the unit sat in the original box taking up space in my garage. Then a sorely needed and massive downsizing effort started at my small  house. "Use it or get rid of it" applied to everything we owned. I decided to install the cruise control in the coupe.

 

The installation manual which came with the cruise control was good with respect to the mechanical installation. It  said to locate an accessible area to mount the cruise control servo that provides a smooth path for the cable with no sharp bends, away from hot, sharp or moving objects, and not on the firewall. Have they ever looked under the hood of a '39 Ford? I chose a mounting location high on the left inner fender panel.

  

  

The cable goes down, curves toward the firewall, then U-turns upward toward the carburetors. I used the bead chain coupling (item 24), the bead chain coupling sleeve (item 23), the bead chain (item 20) and the bead chain eyelet connector (item 25) to make up the cable attachment to the rear carb.

I placed the dash control switch in the center of the dash where the stock radio head mounted. The area is too crowded, so future plans call for a new mounting plate with a little better spacing and possibly the removal of the heat and air conditioning on-off switch (left side of the plate). Considering how long it took to get this far, the future plans may never reach fruition.

 

 

The dash control switch had 6 wires coming from it. Four of them (red, brown. green and yellow) plugged  into the male side of  a 4-pin Molex connector (like a hard drive power connector). Both halves of the connector had a color coded sticker on them. The grey wire plugged into the parking light slot in the car's control panel. The black wire was a ground.

There are six wires and a co-axial pair in the main harness which attaches to the control module incorporated in the Servo. Three of the wires (brown, green and yellow) go to the female half of the Molex connector.  The fourth wire (red) into the female half of the Molex connector comes from a 12 volt supply which is hot  whenever the ignition is on. I used a fused hot lead in the panel, so I didn't need the supplied ATO fuse and holder. The blue wire connects to the negative terminal of the coil and  disengages the cruise control when the clutch is pressed., The purple wire attaches to the brake light switch on the stop light side and  disengages the cruise control when the brake is applied. The red wire attaches to the hot side of the brake light switch. The 15" black wire is a chassis ground. The co-axial pair gray wire is the speed sensor and attaches to the factory VSS (vehicle speed sensor[ if equipped]) or the magnet pickup near the drive shaft (Auto trans, No VSS) or the negative terminal of the coil (Manual trans, No VSS). The black wire in the co-axial pair goes to the magnet near the drive shaft. It is not used if the VSS connection is used, Although the installation manual did not say so, the black wire is not used when the coil (-) connection is used either. A vacuum connection is made from  the intake manifold  to the servo.

I had to use a Dremel  to shorten the cruise control throttle attachment screw so it cleared the idle adjustment screw and spring on the rear carburetor.

I set the DIP switches in the Servo assembly as follows: Pulses per minute: SW1 & SW2 ON  (8000). This is necessary so the cruise control can be set higher than 52 mph. Speed signal: SW3 OFF (tach only) Sensitivity SW4 &SW5 OFF (medium - most cars) I might change this to Low - light cars W/ high horsepower to sooth my ego. Control Switch: SW6 OFF (normally open switch) Tach source: SW7 ON (coil)

On the first road test, the cruise control did not work. Using the trouble shooting section of the manual, I checked the Black wire in the 10-pin connector - grounded - OK,

then the red wire in the 10-pin connector -12V all the time - OK

then the brown wire in the 10-pin connector no voltage under any condition - Oops. 

I disconnected the 4-pin connector and found that the pin on the brown wire wasn't seated in Molex connector. When I pushed the pin in and reconnected the 4-pin connector, the cruise control worked perfectly. 

These units are no longer being supplied nor supported by Audiovox. However, Murphs' Kits

www.murphskits.com is having them reproduced by the original manufacturer (Rostra). The bad news is that they are currently out of stock.

So, what does Suzanne think about all this? The following pages are copies of a four page brochure that she did as an Adobe class assignment years ago.

16 Let There Be Light

The coupe does not have power steering and it had a 13" diameter Grant steering wheel. It steered alright on the road, but it was a really difficult to turn the wheel when it was not moving. Since I have entered my eighth decade and might not be quite as strong as I was when I installed the Grant wheel, my wife decided to buy a Limeworks reproduction '39 banjo steering wheel for my 71st birthday. These wheels are 17" diameter like the originals.

The steering wheel looks great but felt a little loose on my (stock) column. I was able to shim it with electrical tape between the column and key and the wheel hub. The steering effort at rest is much better than before. It's amazing what four extra inches can do.

However, the distance between the steering wheel and the brake pedal was reduced enough so that it was difficult to get my foot on the brake pedal. I did several things to address this. First I adjusted the pedal return spring so that the brake pedal was even with the clutch pedal. Then I made brackets to move the seat down and back. The clearance between the pedal and wheel was better, but I still worried about being able to stop in an emergency situation.

Since the steering column drop is about 1" shorter in a '40 than a '39, and since a stock '40   drop is damn near as ugly as a '39, I decided to use a custom '40 style drop from SoCal Speed Shop. Since I didn't like the polished appearance, I had it powder coated gloss black to blend in with the dash. I also got a 4' piece of 1½" x .035 wall chrome-moly tubing to replace the thick wall chrome-moly tube we used when we suspended the brake pedals from the steering column years ago. The supplier was OnLineMetals. I cut the tubing to length (41⅜") and had it powder coated gloss black.

While I was making changes in the steering column area, I decided to address another safety related issue. The horn button was the old starter button and I had to think a moment to realize where it was. I wanted to put the horn button back in the center of the steering wheel.

           From Model A (1928) through 1939 V8s, Ford's "better idea" for the horn and headlight

           wiring was to have the switch body mounted at the base of the steering column. The '39

           switch wiring looks like this:

The four wires shown in bold type were routed to the American Autowire panel under the dash. The remaining three wires are for functions already included in the panel and are therefore not necessary.I bought a used stock '39 headlight switch, horn button and light switch rod, brass guide, bottom plate and light switch mount for the steering column. Hot Rod building axiom #3 - Don't ever sell or throw anything away that is in any way related to your car. If you need it in the future it's likely to be very expensive. Of course, this axiom is likely to put a strain on your marriage. It can be worked out though. My first marriage lasted 30 years, until my wife died. My second marriage is still strong after 18 years. If you treat her right, she will put up with the hot rods. The sermon is over.

In order to use the horn button in the center of the steering wheel, I needed the light switch assembly and wiring harness. These parts were purchased from Bob Drake reproductions. The switch housing was made of thinner metal than the original and the tines that hold the two pieces together are smaller than they should be. The result is that the rear piece is not secure enough to hold the rear half of the light switch in place. I had to use a hose clamp to squeeze the front half of the housing so the two pieces together and shim the switch plate contact piece with two layers of electrical tape so that it would not tilt in the housing. It is really tricky to assemble the switch correctly.

In the center of the horn button rod is a wire which is insulated from the rod itself. When it is depressed, the horn button touches the top of that wire, grounding it, There is a contact in the center of the light switch which should have a spring behind it so that it touches the lower end of the insulated wire and transfers the ground to the horn relay which blows the horn. None of the parts which I bought contained the required spring, and there was no instruction sheet mentioning the spring. So I had to unsolder the wire from the contact, determine how long the spring needed to be, buy a spring of the required diameter and length, install the spring and contact and resolder the wire to the contact. Also it is a very good idea to check the continuity of the insulated wire before reassembling the steering column. Of course, I did not do that.

Checks - button on light switch end of horn rod to horn rod - insulated
               horn rod button to ground - insulated
               rod button with horn button pressed - grounded
               horn rod button to ground with steering wheel turned lock to lock - insulated

The insulated wire is continuous. However, instead of not sounding at all. the horn sounded all the time whether the key is on or off. The lower contact is isolated from ground .

I tired of trying to make the Drake parts work. I got a hold of a genuine '38 Ford harness and used parts of it to mate with the Drake parts. This required buying a '38-'39 bail and continuing use the hose clamp to hold the housing together. When I reconnected the battery and removed the 9V temporary, the lights and the horn worked properly. I never did identify the ground.

The dash lights only operated when the old headlight switch was activated. Since the parking light contact was on whenever the taillights were, I ran a wire from there to a stock rheostat. The other side of the rheostat was connected to the dash lights. The dash lights then worked with the new stock headlight switch and could be dimmed or turned off when desired.
