Any thoughts

New to me 2003 TJ. Reverse lights don't work. Changed the bulbs, checked the fuses and just replaced the reverse switch on the tranny. I am not a mechanic or have much experience tracking down electrical issues. Got to pass a safety inspection in the next couple of weeks and need help. Anything else I should be looking at that I can do?

Unplug the connector on the trans. If manual trans there are only 2 wires but if auto there are more like 10. Find the violet/white wire & make sure it has battery voltage with the key on (from fuse 7 in the fuse bock behind the glove box). Then you need to jump the violet/black & violet/white together. See if they come on (key still on).

with the tranny in reverse check from power at the lights. If no power then check the wiring connector underneath by the gas tank. If no power check the power at the reverse switch. If no power check power to the reverse switch. If no power check the power at the fuse. If no power change the fuse!! Anyways im sure its a case of a bad connection or broken wire but don't rule out that the new switch is faulty...happens all the time

Thanks. It just needed to be tightened further. A short socket wouldn't fit over the connector and a long socket would not fit as a hanger was in the way. Got a closed end ratchet and once tightened that did the trick. Now onto the other dozen issues. MD SAFETY INSPECTION IS A *****!!!
