other than having to extend some wires, there isnt a difference at the ecu plugs on these engine harnesses is there??

All the wires at the ecu harness side are the same functionally even if they are different color wise??

I wanna say no since I'm sure you can plug an LS ecu into a D15 engine harness if you use it during an LS swap...and vice-versa but gotta make sure due to the pinout/diagram I'm using.

 

nobody?

 

Pinouts should be exactly the same...

There may be a few more or less wires in some places, but the basic wires remain the same.

 

great, perfect thanks! now at least I dont have to worry about wiring colors trying to patch these harnesses back together
