Galant with 2g ecu Options

[ncgalant]

Well this story is long and quite funny if you aren't me. For a while now I've been wanting to be OBD something. My Galant is factory OBD1/2. I knew the only way to make it right was an ECU swap. Since my car uses a 95 CAS I knew that a 96 ECU would be my best bet.

My initial thought was to make a converter harness for it, but I had no luck finding the pinouts for a 94 galant GS. I decided my best bet was to rip out my wiring harness and install a 96 eclipse wire harness. All of that was bought and I prepared for the swap this weekend.

I started ripping out my factory wire harness Saturday morning at around 9. I finished getting it out around 4 and started running the new one in. At that point I had to call it a day because my friend (and ride) needed to go. One day burned, but I figured I can finnish tomorrow and all will be good.

Started in on it this morning but ran into a road block at the relay/fuse box under the hood. My galant connector wasn't even close and the wire colors were even worse. I go on to other things and eventually that problem comes back to bite me. I have to use the old harness. I decided a converter harness was doable at this point since I have both sitting in front of me. I start matching things up and before long I notice that the pins are always in the same spot. I pick up the connectors and holly crap they are the same. The only difference is that my galant only has 3 plugs and the new one has 4. After looking at the pinout sheet I have I quickly noticed that the smallest plug, the one I'm missing, doesn't really do anything important.

I figure what the hell right. I run out with Frank(I was doing it at his house) and we start pluging things back in real quick. 15 minutes later we have the harness back in, slopily. I grab my old ECU. He figured something would be wrong, but it fired first try. I plug in the turbo ECU with one section blank. I yell at him to unplug the MAS so I don't have to futz with the SAFC. Son of a bitch it starts up first pop.

I had just enough time to drop in my 720cc injectors and I was off. She's running like a top now.

Cool! Good catch. Reminiscent of my '90 to to '91-'94 harness swap. That was more for engine reasons than ECU reasons though.
