Hi just yesterday picked up my new x16xe engine with all the things i need for it to go into my car which currently has the x12xe engine. Was wondering if i could use the wiring loom already in the car to make it easier... Are they the same for these engines with them both being 16v there can't be much difference if any? Any help would be greatful thanks.

do it properly and use a x16xe loom, dont cut corners, i have one here if you want it.........

I already have the x16xe loom but im sure they are the same?

Anybody know if there is any difference between them?

Can't find a wiring diagram anywhere?
