Hey everyone, I've searched as hard as possible and ran into many great archives (which I've saved to my favorites, great job guys!! ) So anywayz here's the deal 1999 Honda Civic LX 4dr. -OBD1 LS motor -OBD1 LS ecu -using the stock LX wiring harness -Skunk2 OBD2 - OBD1 conversion harness I have the OBD1 dizzy in the motor and I have the OBD1 plugs spliced onto the LX harness, so the dizzy and the harness plugs right in, but I have an extra wire hanging from the LX harness which is a blue wire and I'm pretty sure its the RPM signal wire becuz when I start the car the Tach doesn't work. So here's the challenge where do I splice that wire into?? The local shop told me to go str8 to the ecu with that wire but I can't find the correct ecu pin out for the OBD1 LS ecu... can u guys help me??
