Retrofitting 87 Saleen with Cruise Ctrl: need help

[calbear]

Hi,

I recently obtained a cruise ctrl bracket (thanks to Mark Matsuko) and purchased some OEM Ford cruise ctrl buttons.

When I tried to install the Ford cruise ctrl wiring, I only have a black and purple wire going to my Momo horn. There is a small yellow wire that looks like it was cut (during the original conversion?).

I did some researching on my car since I remembered back in 93, the Ford dealership replaced the Vehicle Speed Sensor under warranty since it was leaking. Evidently, for speed density cars, only those with factory cruise ctrl had that sensor.

If anyone can help me figure out how to complete the wiring, it would be much appreciated. (it appears that I need the female wiring that also happens to be black and purple). Not sure what the cut yellow wire was.

Thanks in advance.
