It's a very specific question that I think not a lot of people are going to know unless they have directly done a swap of that portion of the harness which is probably pretty rare and obscure.

If I were in your shoes, I would download the free factory service manuals for both and look at the wiring diagrams for those systems. It will take time but I think it is going to be tough to find someone who knows the answer. You could check with someone like iWire - they might be about the only folks who know the answer to something like this.

Forunately, the 818 doesn't use the factory connectors for the fuel pump or the fuel level guage. The only headlight connector it uses is the high beam, which is an easy to find 9005 connector. I would either not worry about the factory harnesses, or use any harness I could find, since you are going to cut the ends off anyways.

I don't think so. The 06 wrx and 06 regualar impreza engine bay harness, and bits of the rear harness is different. The rear harness can be modified very easily. The engine harness is very different.
Again, I'm speaking on the 06 stuff. But, as I understand it, the 06 and 07 are very similar.

You would need a rear harness and front harness from an 07 WRX (06 WRX rear could work, but not 06 WRX front). The non turbo model won't work (without modification) for the rear since it doesn't have a fuel pump controller. I'm not sure on specifics in differences in the front, but almost certainly they are different.

That is all assuming you are going to dump the whole harness in the car. For the harnesses that we're building here we could make do with just the main dash section on an 07 WRX because all of the engine equipment is located in the main bulkhead harness and everything else would be cut out anyway.

ok thx I guess Its just better to look for the correct harnesses.
