Bernie,

I believe there are various iterations of loom in circulation so my experience may not hold true for yours. My loom has several earth ring connectors that need to be connected back to earth, usually chassis. These provide the earth to each section of the loom and are always black wires. The earth connection for the rear of the car is on the loom somewhere between the 2 rear light branches. It needs to be connected to the chassis.

If the lights were working, maybe you've knocked it off during the body fit. Did you actually test the lights by connecting across the earth and feed connections at the lights or did you use an alternative earth connection point?
