Caspers doesn't have the OEM style relay connectors, but instead, has a replacement pigtail with connector and sealed relay that you use to replace the original unsealed relays. For both the AC and FUEL relays, with proper wire colors.
As a follow-up, in reading through the forums about wiring new relays/pigtails, someone posted that GM used black dielectric grease which hardened over time and one could mistake the hard crusty grease for burnt up connector or relay. He mentioned cleaning them gently with solvent. Well, I looked at both my fuel and A/C relays and respective connectors and sure enough, both are in perfect condition once I removed all the old crusty dielectric grease! Took some time and lots of picking with solvent and fine point tool, but saved me from having to replace them unnecessarily! Thanks TBc forum!
