Mike_Zocco Posted July 23, 2022 Share Posted July 23, 2022 Hey guys, I have a damaged wiring harness on my 07 LGT MT and its throwing codes. Me and my friends already figured out this is a wiring issue, not a mechanical one. I bought an 08 LGT (MT) wiring harness off of my friend but then after doing some research, I am getting mixed answers as to whether or not it will work with my pre-facelift LGT. If I install the 08 harness, do you guys know of any issues that may occur? Or should I just stick with replacing mine with another 07 MT harness. Also have been having a ton of trouble locating an 07 MT harness that isn't damaged or costs over $200... damn car keeps breaking the bank. If anyone has some advice and can help that would be much appreciated. Link to comment Share on other sites More sharing options...
m sprank Posted July 24, 2022 Share Posted July 24, 2022 Easy answer is you want an 07 5MT harness. The 08-09 ecm is different than 05-07 so there are harness changes. You can modify what you have, but it will take research and comparing the electrical schematics. 1 Link to comment Share on other sites More sharing options...
