Yeah, just trying to figure out where exactly is the cruise control computer on a 88-89 MX6 GT ATX 4WS. I know it's separate from the main ECU but can't find where it could be. Help appreciated.

It's kinda hard to describe where it is. It's buried behind the dash, near the center. Uses a 13 pin connector (might help narrow it down..there's lots of crap back there.)

Thanx for the reply AntiSUV. Do you mean behind the dash as in behind the instrument cluster or behind the audio headunits? Or behind the dash facia?

It's behind the audio stuff, but I think it's buried pretty far back there. Probably not very easy to get to. If you lay down on your back with your head in the driver's footwell (legs hanging out the door), you might be able to look up and see it .

Mine seems to be connected to the blank switches, on your dash under your speedo guages etc, where the cruise main switch is, my curise is wired into a blank covered switch housing in there somehow, not sure though

if your are talking about the cruise computer,it is on the passenger side right lower panel,directly in front of the door, the panel comes off easily,and the computer has one small connector.the computer in the center consol is the main ecu,the one that controls the engine functions,timing,and all that.

Correction. The cruise computer is located just above the gas pedal. I know this for a fact since last year I was diagnosing the cruise system (turns out I had a bad actuator), and according to the factory manual, this is where it is. Turns out it was right.

Thanx for all the info guys. I am going to look for it at those places. I am under the impression that one lead from the cruise computer has the speedo signal. Am I correct?

Yep. According to the wiring diagram for my '90. You're looking for a green wire with a red stripe going into the control box (or coming from the instrument cluster).

Thanks for that guys. Jwilsonjrs, do you have the ECU wiring diagram for MX6 GT? Could you possibly scan that for me? I am trying to use the RX7 wiring diagram to connect my Apexi Reve meter. Just want to make sure it's the same thing.

Actually, if you have the cruise computer pin-out, that would be more helpful. My email is [email protected]
Thanks.

cruise control and fe3 wiring diagram

I'm doing a motor swap and conversion to 5-speed. Will the cruise still cancel when i touch the clutch like it did when it was auto?

Also, I'm swapping in an fe3 motor:D but my mechanic needs a wiring schematic for the fe3 to do a comparison, in order to do the install. Can anyone help me? If you have it, would it be possible to scan it and e-mail it to me? The distributor on the fe3 is a four-wire long cam, and the f2 has a two-wire short cam. thanks for the help.

Joel
