Brake Controllers by mheggie

I take it by reading all these post, that a brake controller does not come installed with the truck when ordered with a tow package? I have a 03 1500HD Quadrasteer. I guess I will have to install a electric brake controller to use the electric brakes on a trailer? Do brake controllers ever come included with a tow package? By hooking it up to the harness, it used the electric brake wire through the 7-way connector to use the brakes?
 
Any clarification will help.
 
Thanks

Ford has a factory controller and I think Dodge will have one on the 09's.
If you have the factory tow package, just buy a controller with the connector for GM trucks in your year and all ya gotta do is plug it into the harness under the driver's dash next to the steering column. Yes, it's just a plug in. At least it was for my 03 GMC.
I don't know what these guys are doing with connecting wires to batteries,etc.
Factory tow pkg. Simple plug in.
I bought a Prodigy controller.

GM does offer a factory brake controller. It was an installed option on my truck. *shrug*
 
But it is an add-on in addition to the tow package.

Is this why my interior lights do not work on my brand new trailer? My father has the extra battery on his 2500 and the lights work fine but they do not work when it is hooked up to my truck. I do not have a battery in my trailer. I need 12v to that pin to make the lights work I believe.

Trailer brake Light Not Working Not Trailer Problem by skidogmxz800

I have a 2004 Silverado /w towing package. I started having a problem with my left trailer brake light not working. The blinker works fine. I tried another trailer with the same results. I checked for voltage and there was none for the left brake coming out of the trucks factory towing package connector. Occasionaly it does work. I tried a jumper but it did not work right so I took it out and then it started working only to stop working later. It was working tonight and then stopped. I was parked in the drive way so there was no vibration. Is there a board that this goes into that could be bad. This is all right from the factory and I have never had a problem before. I use an electric brake control modual. Can anyone help me?

I had a very similar problem with my 2003 HD2500 and searching here I had found that someone had the same issue with the source being the hazard flasher. I checked out mine and found that I could remove and replace it and get the lights working, move the vehicle and lights would stop working...basically it was intermittent. I purchased a new one (about $100 canadian), against the recommendations of the dealer, and fitted it - problem resolved. The feed for the trailer harnass does pass through this relay. The GM part # was 10383321 and this flasher relay is located on the backside of the fuse panel. I had to remove the panel from around the cluster and then take off the lower panel beneath the steering column to get at it. From there it just plugs in. Hope this helps.

Which plug under the dash would I plug my electric brake controller into? There are 3 available slots. It is on a 2008 GMC Sierra.

Did anyone ever answer your question? First of all, I bet you have cooler, even though you don't have the tow pack. Have you checked closely to see if there is a smaller radiator in front of the large one?
 
At any rate, the towability will depend upon the terrain. Your 1500 has plenty of chassis, but the motor is a bit light if you are going to do hills/mountains. The 3.37 is fine. I would go ahead and use it, don't abuse it, and watch the temp gauge. Don't operate at high rpm for long periods, uphill.
 
I have an '04 1500 4x4 w/3.73, 5.3, and tow package. It pulls my 6500# 5th wheel great, even up most hills. Trans never heats up, and neither does engine.

The "space" is not too short for a 5th wheel. It simply depends on the "hitch box" your 5th wheel has, and the actual hitch you use. Some 5th wheels have "extended pin boxes", which put the box a little in front of the unit. That gives you more room for turns.
 
I have an /04 with the 6.5' "short" bed (not as short as the 5.5'). I have a standard 5th wheel hitch, and my unit has the EPB. I can make lock to lock turns in the tightest circle with no cab contact.
 
GM has the blank in those spots because they do not want to be liable for some idiot crushing his cab.
