Have a 99’ Yukon that I swapped in an 07’ 4.8, 2002 harness and a 411 pcm, tuned with Tunerpro. Having issues with getting the fuel gauge to work.
Tried various pwm settings. Gauge output is on Pin 38 Red, and have continuity to the cluster pins. When I look at the fuel level with Tech2Win, it reads correctly with what’s in the tank. However, I cannot command the gauge to move either.
Is this a bad gauge, wiring or tuning?
Everything else on the truck works great except for the D321 part of the PRNDL on the cluster.
