Hey all,
Idk if anyone is gonna read my profile so here's a quick recap for context: I have a 2G eclipse, that has a 1G's 4G63T in it (I didn't do the swap, it came like this). When I bought it it was overheating and spitting coolant so we've been working on that for the past couple of weeks.
We got the engine back together and runing recently and so it's finaly time to clean up this engine bay. The wiring is horrible and needs to be replaced asap. I went more in depth about everything that's wrong with it on my build thread so I'm not gonna write everything down again, just know that the wiring is bad. I got a recomendation on reddit to join facebook groups and find a harness there since I live in Europe and there is basicaly no cars like this anywhere near me. So I joined groups and asked if anyone had a 1G wirign harness.
I got quite a few responses, but one of the guys that answered also said that I should be looking for a 2G harness, regardless of the engine. He got a little defensive when I tried to inquire further so now I'm asking here, since this forum has always been very kind.
Are the engines realy similar enough from one generation to the other that you can use the newer car's harness on the old engine?
And since the wiring connects to the ECU, can you really use any harness? My car's stock ECU probably has the data on it to run a naturaly aspirated 4G63, since that's what it came with right? Which means they probably switched out the ECUs? Or can you just throw a different tune on the stock one?
I'll have to check what ECU I have in it but I cant imagine its the old one right? Because how would that control a turbo-ed engine if it was ment for the naturaly aspirated one?
Once I do pull the ECU, how do I tell what car/year/engine it's from?
These might all be stupid questions, but I'm more of a fabricator that anything else and as I said on other threads, this is my first project car, wiring is where my already limited skills end so please don't roast me too hard in the comments
