Surge to EoH conversion help
 

Thinking of doing the conversion near future but getting different answers. from hydrastar(factory) and dexter supply stores etrailer, eastern marine.
Trailer is rated at 7000lbs
Dual axle disc brakes
2016 GMC Yukon Xl Denali with factory controller system.

Called hydrastar and said factory GMC controller will not work Also stated I need 381-7073 converter, but it's only listed for 07-11 GMC
eastern marine said system works with factory controller but listed on site says NO.
At least they both agree on need for battery break away kit and 1600psi HOE unit

HELP
Any places for best pricing
thanks

My retired '09 and my "19, both with OEM controllers worked fine with EOH. It will work. You probably will need a controller assist module (CAM) to get the controller to recognize the actuator. You can buy either a Hydrastar or Titan CAM or you can even use a couple of electric brake magnets wired in line and it will work. Big long story with GM controllers, but they are supposed to work with EOH systems on '16's and later as is, but some do and some (most) don't. They were designed to work with electric brakes. It's an easy mod to make the OEM controller work with EOH.

Buy the plug and play version of either. It's a few $$$'s more, but it is very easy install. Zero hard wiring. Eastern Marine and Carlisle were the only places who sold the Hydrastar plug and play version when I bought mine 3 yrs ago. Easternmarine was $50 cheaper than Carlisle then. You can buy it with or without the CAM. I would pay the extra $50 for the CAM in the package deal. Otherwise, if you find you need it, it's gonna cost you over $100 to buy it separate. If you go with Titan, they have the same basic thing. If you decide to go with Dexter actuator, you can use either the Carlisle or Titan CAM.

After calling to check hydrastar I don't need the HB-CAM converter. I'm going for the hydrastar 381-9067, but currently out of stock everywhere. So I wait until then.

I installed the Hydrastar early last year as stated above even if you don't need the CAM converter it is worth getting it. I did not need it but installed it and it does not effect the system. I had to pull my boat with another truck and was glad I had it installed. It is a good option in case you change vehicles.

Even Hydrastar is out of stock? That is crazy.... eTrailer says they will have some to deliver by 8/9, so there is some hope on the horizon. I really hope your factory controller is one that will work with EOH as is. It won't be hard to figure out either way. Good luck. Let us know how it goes.

Exactly!! I don't know if my '19 would work without it or not, but it was already there for use with the old truck. All I did was plug in and go. Brakes worked like a champ.

have a 15 sierra 2500 and EOH works fine on the oem controller, also have a 14 Silverado 2500 and I had to install the CAM trailer has the titan EOH system.

Do yourself a favor and get one of these.

They are infinitely better than any OEM controller and the only thing visible in the cab is the round knob.

In most cases the plug from your OEM controller will plug directly in the RedArc harness.

This unit has a self learning feature and is hands down the smoothest operating controller I have ever used compared to any OEM or aftermarket.

All here and working on install. Anyone have suggestions where I can find a bake hose about 12 inches long with male and female ends SAE? I could make a steel line but would rather have some flex to connect unit to trailer steel brake line.
Or with female/female and I can use fitting.
thanks

I had a local shop make my short brake line when I did my EOH conversion. They had everything I needed and more there.

Ordered 12 inch but etrailer(8/7) keeps push back ship date, So they shipped a 24 inch hose. Would of rather of had 12. BTW local and several others online were all the same can't get!

If you really want a 12" hose, give this place a call. They usually state out of stock in the ad, so they may have what your need. I bought lots of brake parts from them in the past and they are pretty prompt with delivery.

Eastern Marine has them in stock,I was there last week looking at them because I remembered somebody was looking for a 12” rubber brake line.

Ran into a snag..
I could only bleed brakes was with activation manual over-ride in vehicle because hydrastar would run. Even if I ran the gain up to 10
Called hydrastar and said I would need HBA-CAM 381-7073. The issue is how GMC programs the OEM model and has varied over recent years including some 2021 Yukon.

Another member reccomened https://www.etrailer.com/Trailer-Bra...c/RED44FR.html but would I still need the HAB-CAM?

Specs say you can use it with EOH, but why would spend twice as much money for a controller you don't need? The OEM controller works well and you don't have to bother with an install of something different. I believe a couple of us advised you to get the CAM anyway when you purchased, as it would be cheaper than buying it separate. If you needed it, you have it. If not, sell it. There are always guys looking for a CAM. Your choice but the CAM would be the easy way to go. It's only two wires to connect and two holes for mounting screws. You don't have to pay the big $$$'s for the Hydrastar CAM. You can use the Titan or any generic you find out there. Lots of big trailer shops carry Titan and/or a generic a lot cheaper than the Hydrastar and Etrailer.

As stated earlier, it's a crap shoot with GM. Either '15 or '16 models forward, the OEM controller is supposed to work as is with EOH. Earlier you have to have the "fooler" wired in to get the controller to recognize it. Later than those years, who knows. Some do work without the CAM and some don't.

Three or four years ago none of GM dealers had a clue about why the factory controllers would not work with EOH. Their info said no way they work with EOH, electric only. So, you can't go by what they say, as they only go by what GM says. Kind of the same with Hydrastar back then. They did not know. However, in their defense, not many people knew how to make the controller work correctly. At least, it sounds like Hydrastar listened when people talked to them about the issue and are relaying that to customers.

I have that cam you can have it free you can call me Brian 856-863-5635

This is why I love OSO. Great folks.

Deal of the day. Kudos to you.

Almost my exact words when this popped up in my email.
I love this place and the folks that hang out here.

First thanks to "Craney" for sending the Cam module but didn't need it after all, so if anyone needs it I'll pass it along. I had to pull boat before getting the module because Ida storm coming our way. As soon as I started moving, vehicle picked everything up and brake are working. So far I like the EOH system... any tips for setting "gain control" and also any need to change while towing?

thanks

I find when running slower speed that I adjust the gain down. But that is with a old aftermarket unit.

I am not sure if the built in units in newer trucks adjust for speed or not.
