Centech here. Only one ive used but seemed to be great quality. I routed mine a little different to clean it up. If you run the wires through the kick and on the outside of the inner fender yoi could hide the wires completely. Wish i would have. May go back and do it one day. I ran mine unddr the lip of the fenders. It hides them for the most part.
I can get you some better pics of you want me to.
Looks great! How did you run the engine portion of the harness? I just got my first centec harness and it appears they want it to come out on the passenger side and run across the fire wall/cowl. I'm hoping I can de-loom it any pull the engine wires out of the center of the firewall.
