Im going to post this here since it gets more traffic.
5.3 swap from 2004 silverado with escalade dash from 2006 into a 88 k5.
Could someone please explain the theory of operation on this gauge. Or copy and paste out of GM papers.
I'm pretty Sharp but this one has me baffled.
Most everything else works on the dash, all the other gauges work, driver info, ect all but a few BCM related lights.
