Here is a quick overview of my cc install, hopefully this will be useful to someone as it took me some head scratching to get it working right!
First off consult this page, this gentleman did an excellent job at documenting the install:
http://www.ryanwright.com/delorean/ccs100/
The unit is an Audiovox CCS100, with the panel mount switch.
Panel mount switch mounted where rheostat previously was.
Grey and back wires from the module spliced into 12v plug wiring. (black to black, grey to red/orange)
It is important to hook up this ground or nothing will work. Grey wire is optional.
I mounted the unit in the pontoon, on the drivers side.
the main unit wiring is as follows:
Orange (12v switched, 3A fuse) - tapped into my aux fusebox, relay compartment
Red (12v constant) - Spliced into white wire bundle, relay compartment
Purple (12v braking) - Spliced into Green/Purple wire, black connector on bulkhead panel
Black (Ground) - Ground, bulkhead panel, main ground
Blue (Tach) - detailed explanation below
The blue wire is the tach signal wire. It looks for a change in voltage so see that the engine is revving. if you have a stock delorean, tap into the white/grey wire in the ecu compartment. This is the wire to the tachometer, it is pretty much useless to the cruise module so you will not have cancellation when you push in the clutch, it will just hit redline and you WILL need to install the magnet kit on the axle. Two magnets must be installed 180 deg apart from each other. This is the shielded black and grey wires out of the main unit. But the tach still needs to be hooked up, do not leave it unhooked.
My car is not stock, it has a 3.0 engine. I am also running EDIS ignition. I first tapped into the tach wire, and i could only get it to set between 60-80kph, and it did not function well. I did not have the magnet kit installed. I removed the tach wire from the white/grey wire and connected it to coil #1 on the EDIS module, the yellow/black wire. Took it out for a spin and it worked beautifully. I did not need to install the magnet kit, and clutch cancellation works. This should be similar for any engine with coil pack (distributorless) ignition; just hook he blue wire up to coil #1
