Changed a reverse light and now neither work
Little bit of background, I have an 06 z06 (manual tranny).
I was changing lights and when I went to test the new bulbs out, neither worked! from there, I checked the fuse and it was blown so I replaced it with a new one and still nothing.
Now I'm down to the sensor in the transmission which is part number 89060011 for $50 on gmpartsdirect as far as I can tell. just wanted to double check and get other opinions before I start replacing things that may or may not need to be replaced.
I also noticed by the "reverse lamp" fuse that there is a "BCK/UP lamp" thing but I'm not sure what it is and it just looks like there's terminals in it so I'm not sure how it could go bad.
Any insight would be appreciated!

put car in reverse, push the start button without touching the clutch pedal for 15 seconds and this will put the car into run mode without the motor started.
Unplug the reverse light switch from the trans plug, then just the two connectors out on the plug connector with a paper clip. Do the reverse lights come on now? clean the plug connectors and plug the connector back into the switch and check the reverse lights again.
If they the reverse lights come on with jumping the switch connector pins on the plug, but not when you plug the connector back into the switch on the trans, then your reverse light switch in the trans has gone south and needs to be replaced.
As for the reverse light switch, search the GM number on amazon, and you can find the ac/delco switch for around $35 with free shipping instead.
