The Stovebolt Site Forums The Shop Area The Electrical Bay ? from old thread.. about tail lights and such

So this has always been my achilles heal it seems. Running the lights always feels like a gauntlet.

I did find this thread from 09 that I understand but I'm starting to think I need a 3 or 4 element fixture for this frankenstien and hope one of you guys can point or even trip me in the right direction.

Since the front half is an 88' OT PU and the 'tail end' is a 56 GMC my problem is getting from the wiring harness of the front to the 2 on each side separate 1157 bulbs (one in the bed roll one in a 'trailer light' mounted @ the bottom of the 'shaved' end pocket panel.

The rear light connectors on the OT are
Left Right
Turn - Green/B Green/Y
Back Up- Red/B Red/B
Stop - Green/W Green/W
Tail/Park- Green Green
Ground - White/B White/B

The Turn and Back up are on 1- 15A fuse
The Stop is on it's own 15A fuse
and the Tail lights as well.

I've been telling myself there's a way but have only made it 3/4 there at my closest.

I've tried adding a ground line from my insulated sockets (The bed roll light is mounted in a 1"PVC coupling) to the ground in the connector and also direct to the bed -current configuration-

How important is it that the turn signal be a 'closed loop' as it were, returning via the White/B line?

Now as I finally express the problem in print I'm realizing I need a third bulb no matter what... or a fixture that has dedicated ground/return wires to segregate the 3 circuits. Probably a different bulb type as well huh?

Odd. Hey Bartamos, I have this strange desire to delete this post before I even post it... Is there something in the cyberspace?

So from what you are saying, you need three filaments on each side. Just make sure that the brake and the turn signals are the bright ones. I would try a test hookup using the frameas ground.

3 filaments meaning 1156 x 3
Or 1 - 1156 and 1 - 1157

There are 4 elements in 2 1157's
I have 4 1157's or 2 per side top and bottom for clarity sake.

Say I go with top A(Bright/12v element) as turn
and the B(/2V) element as tail light
then on the Bottom Light run A/12v element as Stop and B /2v tail light...

should work or not?

Caso, that would work or you could use 1 1156 & 1 1157 per side.
Use the 1156 as Brake or Turn and the 1157 as the other and tail light
