When we took the engine harness off my 69 Chevelle we found a tag marked 5262 XW. Anyone ever come across that? There is also one on the foward lamp harness but it is not ledgable.

That is the gm id tag for that harness.The dealer would take that code in parts and check a chart to get the part # for that harness. Gary
