Evil malfunctioning clearance lights '72 25' tradewind

[airgead-cana]

So we scraped, replaced and greased all the lights and they all worked but the curb rear clearance light. Tugged a little too hard and the qwikconnect male plug popped right out the 3/16 hole. Screamed cried and fished. finally cut open the closet between bunk and bath and found the green line taped to the skin. Tugged it up to where I could reach it and now the driver side has gone out. I dont know how to use the voltmeter. Does the live line come up from the floor curb side and then go over to driver side light- or is it anyones guess? there is a line going up and a line going down, the male was shoved in to a female connector which was crimped to them both. Wish it was a bigger closet. Stopped short of any more damage.
Any suggestions for tomorrows escapades?
Thanks,
"Silver Can"

The wire runs in the ceiling, goes around the back, and stops at the left rear clearance light.
This happened to us once when our ID10T nephew attempted helping us replace the lights.
