Adding MAF to Stock Truck Harness
Adding MAF to Stock Truck Harness I bought my LS harness a few years ago from a local guy. The only thing I knew he had cut was the map connector. I was recently re-working the harness for my swap and noticed it didn’t have a MAF connector.
I have a 5 terminal MAF plug that I want to install to match my MAF. Knowing I currently don’t have any MAF wiring, can someone explain where I need to wire it in my 99-02 truck harness? I don’t know much about wiring, so the simpler the explanation, the better.
