Third brake light help

[dodgeman2007]

I have a 2007 dodge ram 1500 I just put a truck cap on it and i'm trying to hook up the third brake light. I hook the hot wire to the brake light wire on tail light wire on the truck. But that wire also controls the turn signal. when i push the brake it works but when i turn the turn signal on the third brake lights blinks. Just can't get it to work right. Hope hope someone can help me out Thanks.

The tail should have 3 wires......try the other one

It does have three wires, the only problem is its a ground, a turn/brake, and a running light. To OP: The only way to make it work with just the break lights is to run it to your 3rd brake light. The 07+ lights are a pain to wire up any aftermarket brakes or light bars.

thats what I thought really don't want to do that. I like to keep all the wires hidden.
