1967 Impala tail light wiring

I need some help with rear tail lights on a 1967 Impala. I installed new bezels and 3 new light sockets, one was already replaced. Wired what I thought was right, and every light works, except if the right directional is on I lose the brake lights on the left side only. If I have the left directional on the brake lights on the right stay on as they should. The only thing I noticed was on the right hand side, the original inner light socket had 3 wires, but 2 went together on one terminal. So on the new light socket I twisted those 2 wires together and joined them to the new light socket. Any advise would be really be very help full.

From memory; there should be three separate wires going to the lights. One is the back up light. One is the directional turn signal and the brake light; and the third wire is for the tail lights. None of them should be twisted together.

Big Dave, Thanks, but that does not get me any closer to solving my problem. There is a single wire for each back up light and they work fine. All of the tail lights which are for lights,turn signal, and brake lights have 2 wires, except the inner most one on the right had 3,but 2 out of the 3 went to the same terminal of the light socket. I only replaced that one because it fell apart when changing the tail light housings. Every light worked before I just wanted the new bezels. Is it possible that one of the housings is not grounded now? How would I check that out?

I had the right and left worded wrong. When the right directional is on I lose the brake lights on the left.

1967 Impala tail lights

Well, I put a whole new rear wiring harness in, and still have the same problem. All lights work, except with the Brakes on and the right turn signal on, the brake lights on the left go out. Every other combination works fine. This is tough for me because I understand mechanical things fine, but strange electrical problems drive me crazy. Could it be something on the steering column with the neutral safety or brake light switch?

Yes, it could be in your steering column, maybe the turn signal switch. Call Donny at AAW. He is an expert and B-body enthusiast. And I'm pretty sure he is on this forum.
