Are they any difference between the jdm rear harness vs usdm rear harness ? Zenki to zenki

yes, significant. US models used an air flow meter to set fuel flow, while the JDM models used manifold pressure(vacuum) to set fuel flow. Completely different systems.

Thanks for the response, that i know. What I'm talking about is the rear body harness that controls the rear lights, brakes and blinkers and such

I believe these are also different. For one, the taillamps use different harnesses, and different taillamps.

I can confirm they're different as well. I don't have any first-hand experience with a USDM rear harness, but I found a couple wire color differences between my car (JDM) and my US electrical manual. Nothing complex though.

Thanks guys for the confirmation. I decided to clean up the stock sr5 rear harness and just wire tap into the fuel pump outlet on the GTS dash harness fuse box outlet. The oem way. Thank you all
