Okay, Just purchased a used 2007 Yukon Denali. Well-documented service records but time for plugs/wires. I swapped them out but found an electrical connection that goes to nothing in the engine bay. Located on the driver's side close to where the firewall meets the fender. Looks like a 6-pin connector. Next to that are 2 wires (approx. 12-14ga) that seem to be cut off and just taped on the ends.
Any ideas?
