Where to find a harness

im wondering where i can find a wiring harness for an ej20h, ej20t & tt engine and an ecu for the 5mt tranny..

i haven't had much luck

should get one when you get the engine.

I can get you an ECU, but not the harness.

You might be able to sneak one through Rinkya if you have a bunch of money and patience.

EJ20T and EJ20TT aren't valid engine codes, try again.

Unfortunatelly in this case, you must be specific. Properly specific. Right down to what year AND transmission EJ20H, as there is 3 possible harness for that engine.

i didnt really have specifics, just looking for a general place to look

You won't be able to buy one, let's just say that much. But they aren't hard to make.

Lets say for example, you have a 94 twin turbo, and want to convert to V3 STi single turbo. For this particular example, you will need a TT4-plug to 3-Plug harness. You would hypothetically need to:

Get a sacraficial 4-plug ECU, doesn't matter if it's a tt or a single, all that matters is the 4 female sockets.
Get a 3-plug loom end, any Aucklander could get one one for you in their sleep.
Join the two together, following the pinouts for both instances.

Bingo, harness made. I just so happened to make one just like that. Only mine was single turbo 4-plug, the single and twin 4-plugs are actually vastly different.
