And found this
All the wiring harness plugs (in the engine bay) plug in where they used to except for three of them: One large grey/orange one that used to clip onto the shift selector switch, one big black/yellow one that went to the shift solenoids on the front of the tranny, and one little two prong one that went to some little switch on the driver side of the tranny. The rest of them plug in the same way they used to. The cruise control will work fine with no modifications. You need to use the MTX ECU though.
To get the reverse light to work, run the two wires from pin 4 and pin 1 on the big grey/orange plug to the two wires in the white plug that should be on the front or top of the manual transmission. To bypass the neutral safety cutout (so the car will start), solder the wires that go to pin 6 and 9 together. The pin numbers for the grey/orange plug are as follows....
Looking into the FRONT opening of the plug.
| 5-4-3-2-1 |
| 9-8---7-6 |
Someone else listed the numbers on the forums once before, but it was a little confusing cause the diagram shown in their post was if you were looking at the BACK of the plug (where the wires go into it). It took me a while to figure out why my reverse lights didn't work.... its cause I reversed the wires and actually had wires 5 and 2 going to the reverse switch. (oops!)
The reason you shouldnt start the car in gear if you bypass the neutral safety switch is that if you are dumb and dont push the clutch in while you start the car, its gonna start moving while you're cranking it.
Oh and the clutch safety switches both plug in easily... the plugs already exist on the AT harness (I wonder why though?). I dont know whether or not those plugs actually are wired to anything, so the switches might not function anyway.
As for the three plugs that used to go to the automatic shifter in the center console... just let those dangle. The same with that one big black/yellow plug and the little two prong plug in the engine bay... just let those dangle. They wont be needed anymore @-
Sorry to drag this post up from the dead.... i just had to reply with my .02
