Brake light on intermediate?

I,m a bit pussled.
All the wiring diagrams show the wiring of the brake light, but there is none on my speedo cluster.
My original cluster only had a high beam and turn signal indicators, with an aftermarket light on the dash for the brake warning light.
My replacement cluster have got turn signal, high beam, oil and amp warning lights.
What do you guys do for the brake warning light?
What would be the OEM solution?

 

It's not very likely there are very many guys here that are familiar with the applications used in 75 AMC X-military. I know I am not. I am asking about your brake warning light and what is it supposed to warn you of? Brake warning lights used by most of our vehicles are triggered by two device switches 1=low brake fluid 2=brake pad wear. What do you think your warning light is warning you of? Do you presently have gauges for oil and amp? Wiring in your new cluster will be no problem but need to know what you presently have and are using.

 

My 74 has no brake warning lamp.

 

My '75 has one. It's an indicator light in the cluster. There's a switch in the combination valve (located on the frame rail) that sets off the light if there is any imbalance in pressure between the front and rear halves of the brake system.

Not working on mine (part of the wiring harness is missing) but present.

 

I want to say that my 74 should have had one located directly above the steering column in that big 1/2" hole.
I want to say it was wired to that switch in the proprtioning valve to warn of a loss of front or rear pressure.
Mine has the hole and the lonely switch.
My new speedo has the light incorporated into it already
I haven't hooked it up, either way,yet

 

Ohhhhh...That's what is supposed to go in that hole. Mines blocked in fact I have seen many intermediate dashes but have never seen anything in that whole save for something the owner installed. Also seems to be a popular spot for dealer installed plow lights. So I guess I have seen something there...

 

I may be blind, but I don't see anything in that wiring diagram that indicates a brake warning light. If someone is seeing it can you point it out to me?

I've never seen a light installed in the blank hole above the column. Earlier CJ's had a manual choke there and I believe it was a carryover to Intermediates, but I've never seen it used for a brake light.

 

Look for PO 3.651-1, it shows a bulb PO 3.651-3

 

I can't find it on the '74 wiring diagram.

It's clearly present on the '76 diagram - IIRC the '75 diagram is similar, but I don't have it here at work.

The bezel for the light in the drawing above kinda looks like "BRAKE" but I'm not sure. I don't recall the '74s having that light. Pretty sure my '73 did not, and I have only seen a plug in that hole, that I can recall.

 

"PO" means "part of." The assembly is 3.651-1.

Can't look that up at work - or I would.

 

Thanks, I looked at that half a dozen times and kept thinking that was the ignition switch.

Wonder if that light was optional? Because my 74 is as completely stock and original as any I've seen and it surely doesn't have that light or any of the wiring.

This thread also has pics of a completely original 74 dash, with no brake light: http://www.earlycj5.com/forums/showthread.php?t=22507

 

This dash looks like it has it:

Picture was of a 71 dash

ETA: I don't think this is a 74 dash, disregard.

 

My '74 had the light over the steering column but it got lost at a friends house when I rewired. I still have the bottom half.

 

Mine has a plug in that hole,too.
My proportioning valve has the switch, but nothing was plugged into it and I found no evidence of any of that wiring harness ever being in place.
I just looked at my 1974 sales brochure and the pic of the CJ dash clearly shows a plug in that hole... no light!

 

Mine had a light that was a quarter turn type installation like the factory ignition. Push and turn. My friends kids got into one of the boxes that had the lights and lost the lens / female half.

 

What was your build date?
High or low "JEEP" on the side?

 

Mine is a June 74 build date. Jeep on the side is still high, hadn't moved low yet.

 

3.651 is definitely a brake warning light. The part had been around for a while, having a Willys/Kaiser era PN (934064). Interestingly, the '74 part applies to all models, not just the CJ. I expect it would have been installed on the lower switch panel on the FSJs, on the same plane as the light and wiper switch.

There is also a '75 part 5456563 which has an AMC era PN and which only applies to the '75 CJ. Does not have a group number, so it's a little mysterious.

 

Might find them in a DJ.

 

Pretty sure the FSJ had the brake warning light in the cluster. I know they did by 78, but not sure if 74 did or not. My dad has a 73 J4000, I'll have to verify at some point. I can say for certain that his J4000 and another 73 Wagoneer we used to own did not have a separate brake warning light in the lower switch panel, if they had one at all it was in the cluster.
