89 YJ rebuild: taillights not working properly

Left taillight works on 3 of 4 function while right only works on headlight. Left side works on brake, lights and indicator; no reverse. Right side only works on headlight. Replaced with new units and bulbs. Problem continues.

First question - what exactly does..'replaced with new units' refer to? Does this mean the entire tailight assemblies were replaced?

If yes, then start at the tailights themselves, and test for wiring integrity and continuity - using an electrical / wiring schematic and a volt-ohmeter.
