Hi, I have a 2003 Duramax and bought a used tst powermax cr and remote off of a used classifieds section. The problem is it won't show the boost and I noticed 4 of the harness wires were cut. I don't want to wreck my computer by randomly hooking them up and I phoned tst and they won't help me because they don't make them anymore.Would anyone have a pin to pin wiring diagram or even have a used harness around for sale? Thanks, George.
