hey 6gc,

I have another update to share. A few weeks ago I sat down and tried to get a jump on some of the wiring needed to get this project going. Overall it was fairly straightforward except for the fact that I ran into several different colors of wire at the st204 EA1 plug which weren't consistent with what the gt4 chassis manual was telling me. I checked the '95 usdm diagrams and they matched what was in the gt4 chassis manual, So I started to suspect that post obdII cars are wired slightly different. So I went ahead and ordered the 1999 usdm wiring manual for $20 and went to town as soon as it showed up. Here's just a few photos of the mayhem:


First things first, gotta get organized.



Things get confusing really quick so I wrote down all of the EA1 pin numbers and attacked them one by one. I got all of the circuits matched up and figured out all of the color issues. Pin 12 on the st204 EA1 had me worried because it was taking the spot of one of the wires coming out of the st205 intercooler/fuel pump relay box. Luckily it turned out that the st204 wire was just a ground so there was no problem in replacing it with the relax box wire.


This is a photo I took of my st204 EA1 plug as a reference while matching everything. This way I didn't have to keep running in and out of the house haha


Here's a picture of the mini harness getting tested for continuity. For those of you aspiring to do the swap on your own, don't be intimidated by the wiring, because this is all it is. If you can get your engine with the intercooler/fuel pump relay box you're golden.


This is the partially complete supplemental harness (I still have to finish wrapping it nicely). The wire pointing down plugs into the intercooler pump, the loose wires pointing up are extras that get ground and power. To the right is the EA1 connector. All I have to do now is transfer over the pins from the EA1 connector in this photo to the connector that's in my car, find power for two of those loose wires, and ground for the third one. And that's it for wiring in the engine bay. I still have to extend the actual 3s engine harness by 3 feet and wire up the clutch start switch, but that's going to have to wait for another day. When I get all of that done I plan to finish my wiring write up and post it for those who want to do wiring on their own. More to come soon
