Audiovox Cruise Control Wiring

Hello. Nice forum here. I purchased a CCS-100 From a guy at a yard sale. I believe it functioned fine when he removed it. I'm installing it in a 1968 Ford LTD with a 390/C-6. I downloaded the installation manual from Audiovox, and followed it carefully. My problem is the red wire. The red wire is supposed to go from the 10 pin connector on the vacuum servo to the 4-pin connector, and from there to the control panel. At what point is the red wire supposed to intersect the brake light switch? My brake light switch is supposed to get the red wire on the constant 12 volt wire, and the purple wire to the switched wire. The instructions are very confusing to me. As you can probably tell, I'm no electrical genius! Any expertise you can render will be greatly appreciated.    Bert                                          Tucson, AZ

The red wire with a fuse holder in it goes to the battery side of the brake switch (hot side). From there it goes to a 4 pin plug in the cruise harness (Outside cavity). The other side of the 4 pin plug is for the cruise lever. The red wire matches to the red wire in the cruise lever harness and feeds the lever with 12 volts. The brown wire from the cruise lever mates to another red wire (2nd cavity in plug) in the 4 pin plug. This wire goes to the cruise and turns it on. the brown wire in the cruise harness has a fuse holder in it and connects to an ignition source to power the cruise. The violet wire hooks to the switched side of the brake switch (has 12 volts when brake pedal is pressed). Do to the age of your car, you will need a speed sensor kit added to your car to supply the cruise with a road speed signal. You may be able to use a speedometer cable style sensor or a magnetic pick-up style sensor on the drive shaft. sparky

Hi, Sparkie, and thanks for the response. The guy I bought this thing from really snipped up the wiring harness, removing it from his vehicle. The instructions I downloaded don't have a complete wiring diagram, but they call for a fuse on the orange wire, going to a switched 12V source. Should I change this? The fuse that is attached to the orange wire is a 3 amp. I already have the whole magilla installed on the car, including the driveshaft magnet & pickup. I left the wiring until last... Probably a good thing, or I would have given up a while ago! LOL. I found a Rostra wiring diagram I am tempted to follow, here on this website. Is the Rostra system the same? If not, is there a complete diagram somewhere for the Audiovox unit? Thanks again, I'll look forward to your response.        Bert

If the cruise is a an Audiovox it was made by Rostra. I don't recall any of their cruises having an Orange wire and I have been doing them for a long time. It would be better to hook the fused line to ignition power when in doubt. This will prevent a battery draw and the cruise really won't care. If you can describe what the cruise looks like it may help to identify which one it is.sparky
