OK, guys, let me preface this request by saying, there is probably a simple solution to my problem and I feel a little stupid asking this, but here goes.....
I am wiring up my coupe using a "Keep It Clean" harness. I am trying to wire up the tail lights. The tail lights are 1948 Chevy, single bulb/double filament, so there are two pigtails (one black, one green) on each bulb.
The wiring harness provides one wire for each; R/R turn signal, L/R turn signal, park lights, brake lights. OK, so I assume the park lights are run in series to the black wire on the bulbs. The turn signals are run individually to either green wire on the bulbs. My dilemma......how do I run the wire for the brake light?
If I run a single wire in series to both tail lights, when I flip on a turn signal won't it backfeed to the other turn signal as well?
I hope I descibed this well enough for you guys to understand. I want to get this right before I start cutting and splicing.
BTW, the schematic that comes with the wiring harness shows seperate bulbs on each circuit.
Thanks in advance, guys!!          Jim

The brake light and signal lights use a  common filament which is the brightest one of the two. The break light switch is run through the signal light switch and it controls both brake and signal  circuits depending if you have left or right signal on in order to override the brake light if the signal and brakes are on at the same time. If you can post a copy of the diagram I can tell you what you need to do. What are you using for a signal light switch?

Moose, thanks for the quick reply. I understand the brake and signal lights use a common filament. I am using a Flaming River steering column with Chevy turn signal switch. The brake light switch is a pressure switch that screws into the top of the proporthioning valve.

Your post is making me think..........maybe the brake light wire doesn't go directly to the bulbs, but is routed through the brake light switch...hmmmmmmmmm. Unfortunately, I am in work and don't have the wiring diagrams or the ability to post pictures. Thanks, Moose

Here is a typical GM steering column ,signal and brake light setup. I would think yours should be about the same.

Thanks for the help Moose, I got it figured out. The additional brake wire is only used when the brake lights are seperate from the turn signal bulbs.
