Little wiring help... DC2
I'm currently working on a 95 DC2 GSR that had be heavily modified by the previous owner. Right now as it sits it has a LS motor (without vtec of course) running on a P75 ECU. On ECU plug A there are two wires tied into the harness at A25 (IGP1 Power Source) and A26 (LG1 Logic Ground). My goal is to eliminate these wires that he tied in, yes tied in, not cut, and trace the original wires back to source to find out why it won't work on it's own.
Anyone know where these 2 wires originate from?

Re: Little wiring help... DC2
Thanks for the reply. I found the other end of A26, or at least I believe I did. Ohm test read some outragously high number but the car ran perfect with me grounding the other end. A25 is another story. There's no power to it with key on or off. I can run 12v to it and it will work fine. I did an ohm test between the ECU pin and a yellow/black wire over at what I believe is the main relay under driver side dash, read 2.7ohm. That yellow/black wire is 2 wires together going into the back of a plug and has constant 12v key on or off.
I'm also showing a code 1, just 1 long blink followed by long pause over and over. Resetting the ECU now to see if that goes away. Any more ideas?
Also, this Chilton's wiring schematic is showing that it just needs a 12v source with the key on, is this so?

Re: Little wiring help... DC2
The code 1 is actually a 10 a long flash is a 10 a short flash is a 1
Code 10 is for the o2 sensor not a really big deal but it should be hooked up and or replaced
A26 should be a ground at all times
And A25 shold be hot until the coil inside the pgmfi main relay is energized then it should turn to ground to complete the circuit of the relay
If you can trace the wires that are tied in from start to end and give me a little more info ill be able to help more
