So I picked up a project 2003 Wrangler X. As I'm working through stuff to fix I find that the reverse lights have been wired to a manual dash switch. I did look and there is a backup switch installed in the side of the transmission. The plug is still on it. I assume the switch went bad and one of the PO's didn't know how to fix it. I have ordered a new one and will replace it. Here is my question. Where am I likely to find that they wired the manual switch to, to undo it and have it function properly. I assume there can't be more than one or two ways to do what they did. Where should I look? TIA
