Larry... like Wes said above, you can just cut off the high beam (2-prong) connectors or trim them out. That's what I would do, if you need a harness for a Chevy. The remaining 3-prong plugs have high, low, and ground for 7" single headlamps.

Or just sell the harness. I doubt it could be returned after that much time.
