These are custom made to order. Expect to send in your original harness, and minimum of 10 week wait time.

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. Expect to need to send in your UZ harness, as well as your intended chassis' factory engine harness, depending on which it is. Connectors typically do not get reused from the original harness'; we just need them to verify connector type and length as the UZ engines have a variety of harness differences depending on year and 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'. On Toyotas specifically, the factory chassis ECU gets retained for MultiPlex compatibility, meaning the factory ECU will control the A/C, gauge cluster, throttle, auto transmission, ABS, etc. Feel free to reach out to us with what your swap is and we can make sure you get the right price and harness for your application!
