no brake lights

[bigdumbfun]

I have a cherokee that I put a hitch on and bought the flat 4 pin plug that mates up to my trailer plug. The wires were clearly marked;

-ground
-R.turn
-L.turn
-tail

So, I wired into the Jeep at the tail lights and I have everything but brake lights. There was no brake light wire and I wondered about that. But thery all work when I tow the traileer with my Explorer. What did I miss?

Thanks

If your Cherokee has amber turn signal separate from the stop lights you'll need a module. They basically plug into the stock wiring harness. The brake lights on a trailer just use the turn signals together.

Aha! That totally makes sense. Thanks alot, I think I know where to find a module.
