hi guys i'm new to this forum and am looking for help with a project of mine so any help would be much appreciated.

START READING FROM PARAGRAPH TWO IF IN A RUSH

So here it is I brought my first car from an auction over a year ago now and all I knew about it was that it needed a new clutch and cambelt. I didn't even drive the car before I brought it (rookie move i know but payed off). so the car has been a real pleasure to own. i'm loving the way it drives, sounds and looks. but recently while giving it a bit of a heavy foot and hard shifting i have blown my gearbox. so being the young 19 year old i am i went out and brought a turbo engine for it at the same time.

So i have brought a full engine loom and ecu out of a st215 caldina (3sgte) and i know that it will bolt straight in (i think) thats the easy part the problem i kow im going to have is the wiring. so what im looking for from you guys is any tips and other probems im going to run innto. also if any body has a wiring digram from a st202 3sge celica and one from a st215 3sgte caldina that would be much apriated. before any of you guys try and say ive chosen too big of a job the sort of person i am will not let it get on top of me and i am planning on trying to get this done before my summer brake in about 4 months. i am training to become a auto eletrictian so have access to plenty of peole to help but am wanting to do as much on my own as possble.

also if i can get any recomidation on other upgrades which would suite this build well would be helpfull. such as coil overs, brakes and gearboxs. j

you shouldnt have to do much to the body harness. just compare the ST202 and ST215 wiring diagrams. it should be fairly similar to 3rd gen. with more wires. since 4th gen has COP and more sensors
