3sgte 4th gen swap, Hello I am trying to swap my Toyota Celica 97 gt to a 3sgte 4th gen Options

[Tmiller]

I have the 3sgte 4th gen engine on the way and getting things ready to go! Looking for help and ways to get it going ! Right now I have done alot of research and talked to tons of people. I was wondering if I could get some help with my project . Right now I'm planning on running the engine stock I made sure it came with the 3sgte hanress and ecu and im getting a flywheel and clutch kit . Iv been looking around and doing research and I might attempt my wiring harness myself I have two harnesses and I might just try it . But I also need help from people that have experience with the swap and the 6gen community. Helping me find parts, and help me get it on the road with a wonder build ! I hope this goes well , would appreciate all the help I can get !

ok the basic approach to wire a swap that i took is easy.

A car is an electrical circuit like any other. and the job is to integrate new engine into the cars existing electrical.

1. First and foremost you need the celica EWD wiring diagragm book
2. Need the wiring diagram of the engine control of the engine to be swapped.
3. Understand the importance of grounds and their locations, these must not be changed.
4. Understand the importance of shielded wires and their function. dont skip on these.
5. Relays, how they work and their use, and the different kinds of relays the celica has.
6. Proper way to solder wires.
7. beleive it or not, extra, extra donor harnesses, to get the color wires you need and appropiate gauge... (keeping same color wires, helps to trace them..)

next is to understand the celica engine harness. Connects the EA1 plug and fuse box to the engine and to the junction boxes underneath the radio, they have a name, dont remember.... lol

the wires that come from the engine need to be removed. you wont need those. you have to integrate new wires from new engine, into the existing celica engine harness.

Understand the functions and why there are junctions, fuses, and other little nifty things here and there.

The way i tackled is i drew a road map. and that helped a lot. took 2 weeks to do it, but i can wire as many 2grs as i want just by following it...

i added relays on mine, and used existing relays for other needs as i felt comfortable. almost all relays do the same function, except the Circuit opening relay and some fan relays. Most relays use a low amp current to operate a high one....

at the end came up with this...

and now i have my own path, that i followed. At the end, i found mistakes, but i knew where to look for them, and a single ground, prevented the engine from starting.

A 4th gen engine is not going to be complicated as this one....trust me. I had no experience...., but i had lots of determination....

Good luck...
