[gmc684x4]

Thanks Vic
That was my thoughts it should work

I remember when i was looking up cs upgrades it was suggested further changes where needed for the cs144

My harness already has been properly re worked to stock style si wiring i have picked up the eclin wire harness adapter with resister from napa

I like to make my wiring look factory
I started doing that 30 years ago as i fixed my 68 harness several times
