shift indicator switch?

[90bronco2]

I have these two green wires that are pretty chewed up on my transmission, I'm thinking they might be a shift indicator switch, but I honestly don't have a clue. The first picture (only one red arrow) shows the plug, then it wraps around where my shift lever slides into. The second picture (two red arrows, and a green arrow) on the other side of the transmission shows the wires with red arrows then the green arrow shows what i think might be the switch. It looks like that switch might unscrew. Any suggestions?

sorry

My bad on that description of photos, that one green arros shows where the shift lever goes just for reference of where that switch is
Thanks

For anyone looking at this thread, this is not the shift indicator light, I have just found that it is the back up light. Kinda feel pretty retarded that I didn't know what it was, the location of it makes perfect sence.
