6G Celicas Forums

Im in the way to finish my 7afe to 3sgte engine wiring harness but still having a very,very,very,very big problem with the engine wiring harness.I know that the wiring harness need to be lengthened like 30" inches but what about the plugs,the one that go to fuse box in the engine and the others from the acesories inside of the car,the two other plugs,remember I have a 1994 celi with 7afe engine.I need the help from anyone who has done this before to help me with this.Waiting for answer and help alex3sgte

IM Qatar11 for help.

mike is to busy these days to do harnesses, unless your willing to wait for it. Otherwise you need to pic up wiring diagrams for your celi and from the celi your swapping from.

sorry but thats a bad idea.

i tired to get info from him about wiring. his reply was that it was how he makes money and that he would not be able to give away information for free.

alex, call 1.800.622.2033 and order 2 electrical manuals. one for the alltrac and one for the year celica that you have. then you should be able to figure out what needs to be done... i placed an order for mine and im hoping that it will be enough info in there for me to figure things out.

what we really need to do is have this comunity step up and do a full tutorial on wiring for the 3sgte. everyone i have tried to talk to about this, basically acts like its some big secret and dosnt want to provide information.

my advice to you would be to drill a new hole in the firewall and try not to change as much of the harness as you can. the more wires that you modify, the more chance you have for problems down the road.

also, from what i understand. all the plugs inside of the engine bay do not need to be modified. the only ones you have to mofily would be inside of the car. the reason why people say to extend the harness is because those people are not drilling a new hole in the fire wall. if you drill the hole then the most youll have to do is extend a few plugs....keep in mind that i have not done any of this yet...this is just info i got from people.

all you would need is those 2 diagrms, a volt meter, and a little know how... not that much. Ohh and some time. Basically all you have to do is convert the already there interior plugs from a 185 to the interiour plugs for your at200
