Finally, a full harness for your V8 swap to make things much easier! We've done more than a few over the past decade, and now we're teaming up with the renown Dr. Tweak to offer a top shelf harness and their lifetime warranty!

These harnesses are all custom made for each individual application, so in many cases, we will need a core harness to start with. If you need a chassis specific harness, please contact us and expect it to be an extra $200-$400, depending on the chassis.

Please contact us and let us know directly what your application will need regardless, and we'll be happy to get another UZ powered vehicle out there tearing it up!! As of right now, we only have support for automatic transmissions if you run the factory ECU for them. Standalone applications will require a dual ECU setup in most newer 1998+ chassis'
