Need wiring diagram for 84 cruise control Posted by DDJ [Email] (#3297) [Profile/Gallery] (more from DDJ) on Mon, 31 Jul 2023 15:00:44 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Hi all,
I have an '84 8V Turbo, which I'm working my way slowly back to spec. Next item is Cruise Control. I had an aftermarket ECU made in Toledo that came with the car that used a sensor at the driveshaft for speed data. It was no longer working and I managed to find what I believe is a stock replacement, which is a gray plastic box maybe four inches square, half inch thick containing a circuit board and a female plug for 9-10 wires. My shop manual seems to show only the 86-88 version of the ECU, which is a metal relay-looking thing, with nine wires going to it. And trust me, I have the REAL set of shop manuals!
So, two questions. First, does anyone know where I can find the correct wiring diagram for the '84 big gray plastic box? Second, could I use the 86-88 version in its place?
This is the last remaining item to be fixed before I can finally put the dash back together and get back on the road. Any advice or help would be greatly appreciated.
Thanks!
David
