How far in the wiring process would this be if i bought it? I want to do this swap with a USDM motor for simplicities sake, but this sounds tempting if a lot of the wiring is done.

What model car would you install it to? If it is going into a GC, the wiring will be easier than a USDM swap because it is designed for the GC chasis and not the newer chasis. Less would be required for sure in terms of wiring, but you would definatly need some electrical wiring skill to be able to complete this properly.

Your link got shortened. Needs the complete url, not the displayed text from whatever forum you got it from.

Anyways, if it's a JDM motor, you're gonna be cuttin' and splicin' unless you get the complete chassis wiring- in which case you basically have to disassemble the whole car. Personally, I'd vote for cut-and-splice. As long as you can get diagrams for the motor you want to install it's pretty straightforward, just time consuming.

Its going into a 94L and where would i source wiring diagrams? Local dealer??
