i have a 95 with a 3 wire coil pack and a rev ms2 basic. no tach after hooking up ecu. I know others have had the same issue but after lots of digging I didn't find anything definitive.

here are some pics of my wiring harness:

1f has the b/w tach wire and 2I has a light green/white mystery wire (haven't tracked it down yet.. my garage is cold)

Tried with and without jumper of course..

I pulled the tach wire and moved it to 2I and just left the green wire dangling to see if that would work. still no tach and car ran funny so I put it back.

I suppose I could buy a 4 wire coil pack, but the plug going to the coils only has 3 wires so I'd have to run the 4th wires.. but I don't know where exactly.

so that's where I'm at. thought I'd make a thread before I spent any more money and tried to figure out how to make a 4 wire pack work. HALP PLZ

those pics are the wrong connector...

youre putting it on 1I, not 2I.

those pics were the 2 different connectors before I swapped them. I swapped the b/w tach wire to 2I for the test

so lg/w is 5vref for tps I believe

okay i see it now. odd.

how many wires are along that top row? should be 13, im only seeing the 12.





Looks like the wire you need is in position 1F. There was some funky stuff that happened between the 95 and 95.5 model for ODB-II.

oh hold on i might be stupid.. be right back..

so for some reason my mind was set on where lg/w was was 2i.. but that was actually 2k. even after looking at that diagram and my harness..

moved 1f to the real 2i and i now have a tach.

thanks anyway though for making realize i derped it up
