I have an '86 GMC Grumman (aluminum body ex-mail truck) with a
transplanted 2001 5.0L Vortec, 4L80E trans, factory engine/trans wiring
harness. Want to use a 2001 Pickup dash cluster I just bought used, and
need a wiring harness from drive train to dash cluster, and tilt
steering column. any one know what model year range that I can search
for to get compatible components. Any other comments, advice??
