Hi Guys,
I am looking at up grading my electrial system in my zuk. Its runnig a diffent motor and a auto. Due to having so many differnt harness and unused wire floating around.
I was gonna have all the electrics done by a auto elec. But instaed i have found a few different aftermarket wiring systems through Rocket industries.
I was wondering if anybody has used them and did they do work for what you needed them to.

I've seen Painless Wiring kits (these are the only ones I know of) used in Street Machine feature cars a bit. From what I've heard they are pretty good bits of kit. I've tried to convince my mate to re-wire his HQ with one as the wiring on that is a joke.

If you don't know what your doing they are not going to be any easier. How they make it easier is having all the necessary circuits already planned out, all the necessary color coding to make sorting through wires easier etc.
