5spdSC300

As some of you may have read, i wrecked my SC300 w/ 2jzgte swap not too long ago so im in the market for a replacment. I came across a non running SC400 thats in my price range. My question is if the interior wiring is the same as a 300?

The wiring im mainly concern about are the plugs near the ecu that connects to the rest of the interior. I want to know if those have the same pin outs as the 300. If it does, it would make my swap so much easier and would just become a plug and play deal.

I have my crashed car so if i needed to, i could pull out the interior harness from it and swap it over to my next car but that would just be a ****** to do. I would like to prevent that if possible. I know a 300 would be plug and play but there's none in my price range at the moment. Thanks in advance guys.

You could ask Aliga if he has 2 harnesses laying around for a 300 and 400 and ask him to see if they look the same...

They are different. Look at my post in "the Big Bad 1jz into sc400" post.

So the only two issues I see are:

the check engine light wiring

and

wiring a 12v source for the igniter and injectors

How about this...Will a 2jz-ge wiring harness plug into an sc400 body harness without modification?
