V8 harnesses can be hard to get.
Getting 2, V6 harnesses might be alot easier, or a V6 harness and then scraps of another for extending wires.

Might as well just use like a 90+ V6 harness and swap on over to SD. The V6 uses the same sensors, and you just need to swap the memcal from a v8 into your v6 ecm to be set for running the v8.

This would definitely be a cheaper way to go. I don't know how well they adapt to thirdgens, but I purchased a Painless MAF harness last year and was very pleased with what I got.
