1UZ Link ECU wiring harness

Link G4X ECU to Lexus V8 1UZ Plug n Play Adapter Wiring Loom Patch Harness 2UZ 3UZ

Link continues to gain traction in the UZ Toyota/Lexus V8 market, and rightfully so! They have an excellent selection of options available, and are an XAT favorite when it comes to engine management. Why pay extra for the AEM name when Link is just as (or even more) capable?? From now, on, you can expect all XAT projects to be powered by Link ECUs.

Each harness is custom made to order, so please be patient as you can expect a 1-2 week wait time for manufacturing typically. Please feel free to reach out to us beforehand and let us know what kind of application this is for. Swapping a 1UZ into an S13 or S14 240SX? Putting a 2UZ in a Tacoma/pickup? Factory Crown Majesta or GS430 getting "the beans?" Let us know so we can be sure to have the right harness made for your project.

This is not for a full engine harness, does not include ECU or sensors. This listing is for a plug-n-play adapter to fit your factory harness, whether it remains untouched or is rewired for a swap. Depending on your plans, you may need other parts as well for everything to work properly. If you're boosting it, you'll no doubt want MAP and IAT sensors to go along with it. Although superior up and down, the VVTi engines also have additional considerations over the non-VVTi, and reaching out to us via phone or email ( is the best way for us to get you situated with what you need.

Please reach out to us with any and all questions, as your application may need more consideration or wiring than standard
