Bartamos, thanks for the info and things to check. I'll start with the first check that you suggested tomorrow. Right now I have the three wires to the rear disconnected at the three pin connector, which basically broke apart when trying to disconnect. I'll have to put things back together with a new connector if you want me to start at the rear lights and work forward. Otherwise, I can start at the wires ahead of the three pin connector. You're the person giving suggestions so your call.
Also, to clarify my statement about verifying the wiring to the rear lights. What I meant was that I verified that the contacts in each socket, left and right, were similarly wired. There are red and brown leads coming from the each of the lights that are connected to the vehicle harness. I was attempting to convey that the wire from vehicle harness for left turn signal was going to the red wire from the left light and the wire from vehicle harness for right turn signal was going to the red wire from the right light. Additionally, the red wires for each light, left and right, went to the similarly placed contact within each light.
Excuse my ignorance, but what's the difference between using the voltage reading function on a multi-meter compared to an ice-pick tester? Multi-meter has ice pick leads on it that I've already been using to check the voltage etc.
