So you want the light to turn on while breaking correct? If so all you need to do is splice into the negative and positive wires of the 3rd break light with connectors like this.

Or use something like this
Cut the 3rd break light wires and install those on the all the wires. Male ends on the antenna and on the 3rd break light so you can run what ever you want. Make sence?

Went to the local auto part store and picked up these 3/4 led lights and wired them up in the spare lugnut holes with quick connectors in case I need my spare.
about 14 bucks and 20 minutes. Had to drill 2 holes for wires and connectors to go thru.

O ya i have used these on other lighting but i just dont know the voltage limit and where the third brake light fuse would be. i dont need a wire going up in flams like what happened in my yj.

ya but if the third brake light is sending to much power it might have a problem with the lights on the antenna if they are over max voltage causing heat and possable fire.

I'm sure it would be fine. It's made to run on a 12 volt system which means it's good for a vehicle circuit. Off your battery will put out 11+/- volts and on with the help of your alternator you can push 13+/- volts. Thats what the light will operate with.
100 watts P.E.P. Transmit and receive with light on or off also means 100 watts Peak Envelope Power which is the throughput of the antenna itself. This also means that you can "talk" over the air without the light turned on.
That being said, you should be able to simply ground the negative to the body and plug in to the positive of your brake light using a splice connector.
Don't follow me, I'm lost too! O|||||||O

No problems. The Leds have such a low amp draw the can bus system doesnt detect them.
They are a 12 volt led so they intergrate nicely.

Don't know the laws for 3rd brake lights in my own state of Md let alone anywhere else, but aren't the third brake lights supposed to be mounted higher up on the vehicle like what would be in plain sight if you were looking at the rear window? Like I said I have no idea but was considering doing the leds on the spare's lug nut holes and I'm questioning whether that is a legal location.
Thanks for any guidance on this.

Im sure the law varies state to state. I didnt even run them in Mississippi.
Recently moved to Utah and had to have them to pass inspection. It passed, so im happy with them.
With a 37 on the back it would have to be almost on my roof for a close following car to see. These are about eye level to the average car.

im in PA and currently i dont have a third brake light on my jeep. My stepdad is a cheif of police and said a cop will not bother you for no 3rd brake light (this has held true for the past 3 months or so) he did say that for inspection i will need to find a way to wire it up so i can pass. other than that its not needed

How's about a write up or part numbers for your mod. I like it.

??? really mine works fine now and its inches from the light as is, and i dont think they would make an antenna that didnt work when it is made to light up 100% of the time not just braking.

Used 2 of these.

Wires ran to old 3rd brake light wires with quick connectors. (Note.) Wires are reversed to work. Black to white. White to black.
Drilled out holes in spare carrier to run wires thru. A little piece of double sided tape to hold them in if needed.
Mine were snug so I didnt need any.
