Using Different Adapter Modules for EOH Brake Actuator on 2008 GMC Sierra

Question

Question:

Hi, I have a 2008 GMC Sierra 2500 with integrated brakes. i would like to install an Electric Over Hydraulic Actuator Adapter Module directly to the IBC for compatibility with all trailers. I am wondering if there is any reliability difference between Dexter DX35FR and HBA-CAM for Michigan with salty roads? I have seen reviews of people installing directly to their truck and also one of the QandAs from Conner L saying that the adapter modules are not brand specific. Also would you have schematics for my pickup and where to find the brake signal wire?

The adapter module itself is not brand or make/model specific. While it would be nice to pair the Dexter Adapter Module # DX35FR with the Dexter DX Series Electric Over Hydraulic Brake Actuator # K71-651, you can also use the HydraStar # HBA-CAM instead. Either will work if you're trying to use it with different trailers, although getting a brake controller with an EOH mode like P3 part # 90195 would be more ideal.

As for reliability difference, I haven't heard anything yet comparing them when it comes to salty roads. The main difference is that HydraStar # HBA-CAM has a larger user base and support and the Dexter module # DX35FR is much newer product recently released by Dexter.

While we don't have your truck schematics, we do have videos when we do install brake controllers like the one I attached below installing the Tekonsha Prodigy P2 # 90885 on a 2008 GMC Sierra. I also attached the wiring diagram for the Dexter Adapter Module # DX35FR to give you an idea of where to wire it in. It will be a different process if you're wiring it directly to your IBC, but the brake controller video explains the general wiring area in your truck.

Answer 1

This is exact same adapter as the Dexter part number you mentioned with the part #DX35FR. Now with that said your 2022 Ford F-250 shouldn't need this adapter so that makes me think you just need to put your brake controller into hydraulic mode.

The integrated brake controller of your 2022 GMC Sierra 3500 has a hydraulic mode which would allow it to work with electric over hydraulic actuators without needing an adapter. With that said if for some reason the controller wasn't recognizing…

All the brake controller needs to sense a trailer connection so that you can test it is a slight amperage draw on the output circuit. For that you can use a circuit tester like the part #PTW2993 with one pin grounded and the other on the output pin.…

The replacement brake pads you need are determined by the caliper that you have on your trailer. The Kodiak Ceramic Brake Pads #K250CP fit any Kodiak caliper with the 250 stamped on them. If you have a different caliper and/or a different sized axle…

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…

Hey Danny, this is a really great question but B and W states that their fifth wheel to gooseneck adapters like the part #BW83RV actually put less stress on the RV frame than a pin box so the warranty would not be affected. Lippert might take a…

Hey Jerry, GM moved the placement of their puck systems starting with 2020 models so you are correct that the pucks would have the hitch not sit directly over the axle. GM did the math and made sure that this placement wouldn't adversely affect…

Hey Dennis! If your fifth wheel uses standard 2" square leveling jack legs, the RVpaws articulating jack pads #RV24FR is the correct kit. If the legs are standard 2" round instead, you’d use #RV57FR. If you actually have Lippert Titan or…
