There is a green plug near the ecu from the engine harness. Can someone simpley tell me what uses that plug? My old hanress didn't have it due to being hacked up and I'm really hoping that this new one fixes all my problems. Thanks

 

That green plug plugs into the dash harness.

 

then that would explain why the vss wouldnt throw a code but the speedo still wouldnt work. so im hoping anyway

 

I have the green plug hangin around my ecu too...I was told it's for pulling codes or something.

 

not the little one though, the is like a wide plug. its plugged in now so im hoping it solves my problem...
