stop light / brake lights

Anyone have a pic of the stop light switch and how the wire is supposed to attach to it? I'm trying to get my tail lights wired back up and the previous owner changed all of the wiring to yellow wire. It's a bit of a challenge. I found a loose wire under the Jeep and I think it's supposed to be my stop light wire that goes to the stop light switch. Thanks

 

NAPA part NO: SL134

I used bullet connectors to hook it up.

 

Its a pressure activated switch, a hot feed wire goes to one terminal ( doesn't matter which one ) when you apply the brakes hydraulic pressure causes the switch to close and current goes to the brake lights via a second wire, Normally connections are made via a bullet connector.

 

Don't know, just asking, does 48 have turn signal and if so are they same bulb (1157) 12v conversion w/stop light? If so you have to wire stop light thru turn sig switch for L and R cancellation.

 

It didn't come with a turn signal from the factory, but some where along the line someone put an aftermarket Signal-Stat kit on it. I found some info on the 3B page, that I might be able to use:

Edit: I'm not sure about the bulb, I'd have to look, but yes, it's been converted to 12v

 

I have a follow-up question... There are two posts on the stop light switch, which is on the front of the mater cylinder. A wire goes from one post to the light. Does the other wire go directly to the battery? Does it matter which post I use to run the wire to the light?

 

I think I have mine tied into battery... this causes the brake lights to work with the ignition off if you press them, I thought this was handy if the vehicle is disabled. I will have to double check.

A lot of people tie them into the ignition "run" circuit so that the brake lights don't come on when the vehicle is off.

 

Seems easier to run it right to the battery. Does it matter which post on the stop light switch I run to the battery?

 

no
don't forget a fuse or circuit breaker

 

X2 run it through the fuse box, or at least run an in-line fuse.

 

Guess I'm missing something? I thought you said you had a sigstat turn sig switch? One wire from fused battery to either term on stop switch (either one) and other wire to turn sig-switch unless you have seperate lights for turn and seperate lights for stop.

 

Here's the wiring diagram for the model 902 Signal-Stat kit.

 

As you can see, the stop lights aren't even on the diagram. So I'm trying to figure out how they should be wired up. It doesn't help that one of the previous owners used the same yellow wire everywhere on the jeep. It's also all wrapped in electrical tape.

 

FYI I bought a fuse block and flasher from NAPA for $30 and 3-4 spools of wire. We wired mine in one night making actual harnesses in that plastic shroud stuff. I think I have less then $80 into it. Though I did have most of the connectors on hand already. Most of the stuff is soldered too.

Might be more worthwhile int he long run.

 

Glenn has it right. You cannot use sig-stat diagrams 902-903-905 if (I say again) if you are using a tail/stop combination light. If you remove the bulb and the socket has two little buttons down in the hole, it is for dual element 1157 type bulb. If this is the case you will have to use sig-stat 800 series switch.

 

Okay. So the 902 series signal kit I have is not compatible with stop lights. That might explain why there was an extra set of lights on the back of the Jeep when I bought it It had a set of small red marker lights mounted above the tail lights. I guess those were being used as the stop lights at one time. None of the tail lights worked when I bought the Jeep and the small marker lights weren't even wired up, so I had no idea what they were for.

 

My brake lights are not wired through the turn signal assembly IIRC, and I have combination tail lights :? They seem to work, but I have the wrong flasher unit for my LED tail lights, when I hook up a normal light they work.

I have the black signal stat with the green bar that is supposed to light up.

Here is the fuse block I used ( I haven't painted the jeep yet)
