Ok so i removed the stock fuse block from my truck wiring harness i got with my LQ9. But im worried that if i go throw it in the truck with my swap that it will leave me sorting out wiring nightmares forever. I really dont want to have to mess with it any more than i have to.


So what stand alone engine harnesses you all use? I have the 03' PMC at the moment. Looking for a stand alone engine harness to keep the fuel injections. Something that does not require a whole lot of additional wiring. (just wiring into my ignition and fuel relay and such)

Also what year/truck/DBW setups will work with my LQ9? And is the harness for that separate? Do i need to have the PCM tuned differently based on what setup i go with?
