Save yourself trouble and confusion and send it to Dr. Tweak. He's a member on here. I'm pretty sure he can do that harness for you.

You wanna spend hours upon hours looking through vague manuals while being frustrated and confused and possibly screwing something up? Pay to play bro! He does harnesses in like 2 hours and is a complete professional. Ask anyone on this site who's had him do their harness. -------------------- taking too long to mod since '09

I know $600 sounds like a lot, but Dr. Tweak does this stuff every day. If I had a cut harness, I'd be getting a big enough box to mail it to him. I wouldn't chance it. Bad wiring will screw over your entire swap. Cut wires = engine never starts. Then you've blown all your money on a motor and taken the good motor out of your car so now you don't have any money OR a running car. Just send the harness to Tweak unless you're brave enough to look over wiring diagrams for hours and if you have a second car to drive while your Celica is out of commission.
Forgot to say what I meant to say... Good luck with the swap! Be sure to give us a good progress thread. There aren't enough 4A-GE swapped Celicas around 6gc. I have a project Celica and I totally wish it was an ST so I could do the 4A swap. Good luck and keep us updated!

Just remember, you get what you pay for. Dr Tweak's prices are based on how long it takes us to do the harness, and the difficulty level of it. The more intense the conversion, the higher the price.

Should have washed the bay and the motor. Did you replace any gaskets or belts while it was out?

Let me know how you like this when your done...
And also curious to if you did any of the required maintainance(sp) on the engine while it was out, i know with alot of places you have to overhaul the timing belt, timing belt tensioner, water pump, belts, ignition etc.... and how much have you spent so far just out of curiousity? -------------------- 1996 Toyota Celica Project Mean Green
