I have a third brake light I wanna mount. I tried to use the wires on the light in the back but got a brake light and a signal on one then the other is for tail light only. Do I have to go straight to the pedal or is there a short cut connection. ...TR

 

It may require one of those common-bulb system logic adapters. You could probably run a wire straight from the brake light switch instead and see if that works... or spend the 5-10 bucks on the logic adapters.

I'm also considering buying / mounting a 3rd brake light for safety and insurance purposes... but I'd like one I can bolt/screw into the top of the liftgate, instead of a stick-on one

 

Can you explain the ''''adapter'''' a bit more to me ......5-10 is not bad ......In the brake light there are light 5 tiny xmas tree like bulbs though ......Yes I was luck mine is a screw in type...TR

 

i bought myself a 99 led third brake light i mounted into my liftgate it's flush with my liftgate so it looks nice. it uses trailer wiring.

 

Well I just ran it straight to the pedal '''works good '''''...TR
