So, I've ordered a 1992 ST185 wiring harnes, which should be here in a week or so. I realize the wiring hell I'm going to have to go through to get this to work with my ST165 fusebox. A few questions:
1. I have a 93 JDM SW20 ECU. I believe the wiring harness plugs right into this, correct? Granted, we only have 92 fuel here instead of the 94 it's tuned for, but I can run it off this ECU until I find someone to trade me for a USDM one, right? (The harness will plug right in?)
2. Will I need any other parts from a 92/93 AT to make this harness work for me? I'm thinking mostly things that plug into the harness, like the relays, voltage regulators, etc. I have them all from the SW20, but I don't know if any of them plug into the ST185 harness. I'm only buying the harness, so I need to know what else I need for that.
3. The engine is an SW20 engine that I was gonna use for an FWD celica swap (before I bought the ST165.) I hence bought an SW20 pressure plate/clutch for it. The question is, now that I'm no longer mating the engine to an E153 (MR2T tranny,) will the clutch disc for SW20 accept the input shaft from the ST165 tranny? Boy can I not wait to have a new clutch.
I'm planning on using the 185 harness and rewiring the fusebox plugs to go into the 165 fusebox. Is there anything I should know ahead of time? I'm going to have to rewire the IC pump to work off accessory power, gonna have to rewire the like 5 fusebox plugs, etc. The general question is basically what parts am I gonna need to buy to make this work. This car's my daily driver, and while it barely works right now, it's still functional, and if I get half way through this swap and find out that I need to buy a part, that will suck immensely.
I'll document this project extensively for future swappers, I just really wanna make sure it's going to go smoothly ahead of time if possible.
Thanks!
