In the market for a wiring harness for my engine compartment and under dash. I found keepitcleanwiring.com. Dont know anything about wiring and was wondering if anyone has purchased one of their kits before. Any info is appreciated. It seems to be good option, but like i said i dont know anything about wiring.

To be clear im looking for information on quality of vendor service/product.
Let me know if i should be on adifferent board.
