Installing Trailer Break Controller

I'm pikcing up my new truck tomorrow night (see signature), and I'll have to install a new break controller into it before the upcoming weekend (pulling vacation trailer).

 

I'm told this is quite an easy process, as most everything comes with the truck and is already in place from a wiring perspective.

 

Any first hand knowledge? Any particular suggestions or tips in order to make the process easier?

 

Much appreciated

Do you already have the controller? If not, order the Tekonsha Prodigy and the GM adapter for it. It's a plug and play install. Make sure you get the adapter for '03-'05 trucks.

 

Otherwise, make sure you get the harness from GM, plug it in under the dash and wire accordingly.

 

A word of caution, do your best to try and get at least 500-1,000 miles on the rig before towing, and try to change the oil before the trip. You want to give the engine, tranny and rear axle some break-in time before putting the towing stress on them. This may even be mentioned in the owner's manual, but you can ask your salesman about it when you pick up. My dad was provided those words of caution when he got his new Ram last year.

Installing my brake controller in the 04 CC was a snap, as long as you have the included cable for the adaptor that GM included in the glove box.

Yea, it's a snap. Connect the wires between the harness and the controller unit, plug the harness in under the dash, and pop in the fuse in the fuse box under the hood. Couldn't be simpler...I was shocked how easy it was on mine.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By Atlas · Posted

      GM's are stainless and have a fairly robust powder coating, although, still not worth $850 in my opinion. They will hold up a lot better than their cheaper steel aftermarket counterparts.   What I like about the GM step bars is dealers will often equip their dealer stock with them. Lots of margin. Which means a lot of people end up buying them because they're already on the truck, even if they don't like them. So it's pretty easy to find brand new takeoffs with hardware on Marketplace and Craigslist for about $250.   That's what I did for my crew cab. I wanted ZR2 rock rails for the look, but with the ability to bolt up GM's assist step package. From GM it's about a $2500 accessory all in. The old folks in my life can't get in the truck without steps. I found the whole package on marketplace for $180.

      Forward collision and lane keep assist still a problem on 2022 refresh?

      By kr477 · Posted

      I am really glad I found this post and this site... We have a 2022 1500 refresh LTZ that has these problems: - forward collision avoidance warning light - lane keep assist unavailable - adaptive cruise control unavailable   The truck was bought as a new leftover in 2023, so it was still under the 3/36 B to B when it went in for these problems earlier this year. It has been at the dealer on and off now for about 110 days now. These are some of the things they have done that I can read on the service tickets. - replace/add ground straps (4) - check all battery cables and vlts - replace serial data gateway module - replace front view camera - numerous reprogramming - a few calibrations (apparently ending with 'learned') Last week when I had it back the truck had those 3 warnings every time we used it except for 3 times. On three separate occasions the truck started and ran perfectly with no (zero) warning messages or warning lights lit - everything worked perfectly. Over that same time period the truck did not work on every other 'key' cycle which I would estimate at 60+ cycles. On those estimated 57 cycles it had the same 3 problems each and every time.   It is back at the dealer now - can anyone help at all with what the true problem might be?  Or possibly what can be ruled out leaving a lower number of possibilities? Thank you very much for any help you may be able to supply....

      As for the step bars, friend did just that, bought some cheap ones and we are in Michigan and they turned to rust in less than a year.  In 3 yrs he had to replace one of them because they rusted out from the inside even though he kept after them cleaning and polishing etc. Had to drive 300 miles (to Chicago area) to find a reg cab wt, he ordered one and dealer never got it and with winter approaching (plow truck) he needed fo find one ASAP.  Furd dealer found him one but he choose to drive to get a GMC.    Just what you can expect with cheap stuff, LOW quality.

      Tonneau cover that does not leak water

      By KARNUT · Posted

      I’ve seen many times people over buy to start a business. Instead of quality equipment they buy junk and drive an expensive truck. Our first haul truck was a 2 ton wrecker with 6 cylinder to haul our equipment. It would go 60 miles per hour flat out. Our trucks were older trucks we could work on easily. Our equipment was first class that we could work without fear of breaking down. You could always use large trash bags to wrap for water proofing. Put the money where the return is. Comfort and luxury comes with success. Good luck in your venture.

      Thank you, it looks like I have to get a topper or a box van.  Unfortunately, the only vans that can tow what I am looking for are going to be 3/4 ton vans, which may ride rough if I am going to use this on the road extensively.  I may also use it to take marketing clients out on the road.   Not knowing anything about starting a business, my goal is to start small, use things I already have & keep everything in good working order.  I have a small box trailer, need to install lights in it, and same for the topper itself.   How easy does Chevy/GMC make our trucks to upfit if we decide to add things like a topper and lights?  On Fords, the upfit process was rather easy.  Just tie the +12V of the lights to the AUX relay panel and the - to chassis Ground.
