wiring woes

[Bonehead Custom Designs]

I have a 73 CJ5 that I just got finished doing a body off rebuild on. I Fabricated and welded in new floorpans, Rebuilt Transmission tunnel, fabricated and welded in new stronger body sub floor with custom integrated rock sliders, over all tune up, points, condensor, fuel sending unit, etc. As well as a complete rewire. I used a prefab harness from Northwest Automotive. It's a pretty straight forward harness. It upgrades the harness to a fuse block unlike the original. Granted it's not a plug and play like one from painless. But for the money it's not bad. I have everything wired up and working except for the brake lights and turn signals. I also have a "new" spartan turn signal switch (I also, kept the old one that came off of it). I have two new brake light switches(one for the 73-75 and one for 76-86). just in case I couldn't get the one for 73-75 to work I was planning on making the other one work. I have power coming to the feed from the fuse block for the brake lights. I wired it up exactly like the schematic from the haynes manual says.... Nothing! I've tried several different ways to just bypass everything and isolate the brake lights just to make sure they will function....Nothing! I know there's power getting back to the tail lights because the head lights and tail lights and hazards work. Does it matter which wire from the aftermarket tail lights connects to which wire from the harness? i.e. the left/right tail wire and left/right turn wire. I don't think so but I may be wrong. Anyway, I've rambled on enough. If anybody can offer any help i would greatly appreciate it.

Thanks,
Chip Jordan

Hay welcome to the site. I know some one will get back to you on the wiring issue that you are having.

The only thing that I can think of is a ground issue.

Is this the diagram you used?More than likely if the hots are connected correctly its the grounds.Grounding is a major share or wiring issues.
Welcome to the forum

aside from checking the ground, you never mention the brake light switch. Just because power is getting to the tailights, doesn't mean that power is coming for the brake light. just a thought.

welcome to the site.

Do you have a test light to search down the problem? we can guess all day long but we need to see where the problem originates
a test light for 12 volts will help get us started.

welcome to the site.

Check to see if you have power to the brake light switch. and a test light is your best friend right now, just like mentioned above...

Given that the regular running lights come on, I would say the ground is working just fine.

I'll give an x3 to the using a test light. Check the wire from the fuse block to the light all by itself. Check the circuit for the brake switch too. Make sure it has power and that it opens/closes properly. I'd bet it's the switch circuit.

I'd say brakelight switch also.
I can show you how to make a freebie test light if needed.

That would be something neat to see.

Take 2 pieces of wire make a loop at one end of each then tie the 2 together, the loops hook over a standard 12v bulb like you find in an overhead light.
Not at my comp but will post up a diagram soon to help make it make sense.
