Re: [DML] Audiovox CCS-100 Cruise Control installation instructions

Well, all cruise mods have to pull on the throttle somehow. From my
understanding, many people simply run the cruise line the same
direction as the throttle, wrapping it around the spool from the
front, which can cause binding of the two cables or other problems.

Yes, this was my concern as well, and it's a valid one. The stock
throttle cable will not stay tight around the spool; it will come off
the spool somewhat when the cruise pulls on it. However, my experience
has been that:

1. The stock throttle cable is fairly stiff, and does not just "fall
off" the spool without some coaxing. It tends to stay in a position to
wrap right back around when spool tension is released;

2. There are some metal guides on the spool that help to keep the
cable in place;

3. It took a lot of doing to coax the throttle cable to actually fall
off the spool and wrap around the guides, and I had to pull the
throttle open very far to accomplish this;

4. Installed in this manner, the cruise is incapable of pulling WOT
(wide open throttle); for that matter I don't believe it's capable of
pulling enough throttle to get the stock cable to actually fall off
the spool in any circumstance. I tested this by pulling on the bead
chain after I had connected it to the back of the spool as you see in
the pictures. I pulled as much as I possibly could from that angle,
and the stock cable - while it did "unwrap" from the spool somewhat -
was nowhere near the point of falling off, wrapping around the guides,
or otherwise jamming.

Other than connecting the cruise to pull on the gas pedal up front -
which is a possibility I considered - I believe my installation is the
safest way to get a cruise in a DeLorean without reengineering the
throttle assembly. Now, you must make that judgement for yourself, of
course; I don't need any trouble if someone follows these directions
and has a problem because I overlooked something. It's entirely
possible this is just a ticking time bomb waiting to ram my DeLorean
into another car. But I doubt it; I value my car, my life, and the
property & lives of those around me, and I did a lot of thinking and
experimenting before deciding on this approach. If you get in there,
tie a string to the back of the throttle assembly, and pull from the
angle the cruise would pull, I think you'll find the stock throttle
cable will stay within the guides and go right back on the spool every
time, with virtually no chance of causing a "stuck throttle"
condition.
