Updated Version!

The new version uses a different terminal in the green connector. This ensures proper wire crimp specs. We use a calibrated crimp tool that makes the crimps pass a 20lb pull test. This ensures that all wires stay in the terminals properly, guaranteed!

If you have an older harness, the green connector wires can come loose; we are replacing these harnesses for free. Please contact us for replacement.

We are the ORIGINAL creator of this PNP TB adapter harness. We stand behind ALL of our products 100%.

NISformance is saying a big THANK YOU to our loyal customers! With doing the FWD HR engine swap we discovered the 75mm throttle body. We have been making the adapter harnesses for years now. We continue to fill the market with parts that you simply cannot find anywhere else. Thank you to every customer we have been fortunate to have over the years! We will continue at 110% capacity to fill our special role in the Nissan community.
