Help needed engine harness

Thank you, I’m getting it. I’m learning that you have to unwrap the original harness as the lighting harness is tied into the old engine harness. It’s not plug in play. Takes a lot of time actually. Dealing with old electrical tape. Rerapping, etc. Pain in the *** if you want it to look good.

I think you may find you ordered the wrong harness.
There are some with/without horn harness, depending on your particular vehicle.
