Reverse lights not working

[Prybar]

Not sure what the deal is. Bulbs are good, I checked all the fuses and relays. The other items on the same circuit work fine. Reverse switch maybe? I don't even know where that is. I looked and the tranny is so tight to the body underneath I can't tell what is what and I'm pretty sure I couldn't get to it even if I could. Any ideas?

test power at the bulb. how did you test bulbs?

I do need to test the power at the bulb sockets. I did't do that because I put about 4 different bulbs in each socket. And of course I can see the filament in the bulbs. All looked good. I'm super stumped. It's like a wire broke or came loose or something but I don't see anything obvious.

My first thought was to check the wire harness which hangs below the frame on the drivers side. Also, check the 7 way / pin trailer plug.

Exactly what I am doing now. I'll report back if I find anything.

Wire harness seems good. Not smashed or loose. All wire harness connections I can see and feel are secure.

7 pin trailer plug has no reverse light power to the center pin when in reverse either. I'm thinking reverse switch maybe? Anyone know where it is? Console I'm guessing.

The standard reverse lights have no power or are these flush mounts or otherwise?

I had an issue where I tapped into the harness for reverse lights. Never had an issue, then one day i mistakenly trie to tap into the same wire for bed lights. Reverse lights then shit the bed. Ended up being that fuse 43 blew.

It's the standard stock reverse lights that aren't working. I don't have any aux reverse lights yet. I'll re-check fuse #43. Thanks.

No joy. #43 is fine as is the #39 (or #38?) relay. I'm still leaning toward reverse switch. Just no clue where it is.

If I had to guess, I would think it's part of the shifter.

My guess as well Corona. I just didn't want to dig into the console and be wrong. Seems like someone would have run across it at some point and could lead me in the right direction.
