Tow/Haul button and question

so i read Manual and i shows a tow/haul button and a light for the gas instrument cluster but not for the CRD.

2: if it is will it run electric trailer breaks
thanks

1. Doubtful

2. No. You have to wire in a brake controller to run trailer brakes.

To add to that, if you have the towing package I believe there is a harness pre wired for a brake controller.

how could i tell if it is prewired?
my trailer right now does not have them but our next will.
thanks all.

ya the tow/haul is strange as the CRD has the coil in the spot for the tow/haul light .

There is nothing "prewired" with the towing package as far as a brake controller. You have to wire everything in. I have the towing package but I installed my brake controller.

Reference this post in my build for a walk through:

http://www.jeepforum.com/forum/f67/m...l#post15980009

The only thing that is already there is a green power wire (that sends power to the hitch harness) to the left of the brake switch.

id guess the crd doesnt need a tow mode because it is fine to do it in normal gear ranges. what with it having all the torque low down.

Seems that way. The CRD already runs high in it's RPM range due to the strange gearing DCX paired it with so a tow/haul wouldn't make sense.

You don't need a tow / haul program with the transmission as the CRD will handle any heavy loads without a problem. It's gearing in the tranny is more apt for a gas engine so on a diesel engine it runs the RPMS unnecessarily high and unfortunately really reduces its cruising speeds to 75 mph max or less (runs near 3k at 75-80 mph).
