One concern we had pertaining to the AMP Research Power Step kit, PN10-03057-10 for the '02 GMC Sierra HD 2500 Crew Cab, was the kit came with no diodes. Ox made a run to Radio Shack and purchased four diodes. We called AMP Research to inquire about our concern. Their reply was directly from the AMP Research Power Step application guide:
"Diodes required. GM trucks and SUVs, model years 1999-2002, require four additional diodes that are not included in the standard parts kit. When ordering, please specify the vehicle model year so the diodes can be included. If needed, additional diodes, PN 10-02727-90, may be ordered at no charge and shipped UPS Ground by calling (800) 983-2206." For referrence, you can view this at: http://www.amp-research.com/build/power step/index.asp.
So, be sure if you are ordering an AMP Research Power Step to pay close attention to your specific vehicle's diode needs.
