How Does Hayes Brake Controller install in 2012 Volvo XC60

Question

Question:

Hi there, I plan to install this Hayes-Lemmerz Energize III+ Electric Trailer Brake Controller - Proportional on my Volvo 2012 Xc60. I am having problem figuring out where to connect all the wires. Can you point me to a detailed wiring diagram or video? Thanks,

You will need to start with a 4-way (if you do not have one) installed on your 2012 Volvo XC60 to install a brake controller. For that you would want the # 118739 which I attached an install video for.

From there you would need to convert the 4-way to a 7-way so that you can install the Hayes brake controller # HA81742B. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. The install video shows this installed on a similar 2016 Volvo XC90 which won't be exactly identical but the majority of the install will be the same as far as where the wires should go and why.

Answer 1

On each individual electric brake magnet the amperage draw would be 3.0 to 3.2 max amps at 12 to 13 volts on 7-inch brake magnets and 3.2 to 4.0 max amps at 12 to 13 volts on 10 and 12-inch brake magnets. The max amperage draw for the brake magnets…

Answer 2

I can give you a pretty good idea based on the dimensions of the spindle. Based on the dimensions you listed you have an 84 spindle which would mean you have between a 2,000 and 3,500 lb axle. If the hub is a 6 lug hub then it would be 3,500 most…

I do have options for you but we would not have a direct replacement for your 3,500 Lb Lippert Axle. Instead, we have the Timbren Axle-Less Trailer Suspension System part #ASR3500S05 or part #ASR3500S06 which as the title states is an axle-less style…

If you look at the outermost part of the spindle on your axle there will be what is called a grease zerk or grease gun fitting. It will look like a tiny round ball which is where you can attach a grease gun to grease your spindle. If your spindle has…

Answer 5

It cannot; the brake control wiring is underneath the dash, which is why the Echo Under-Dash (and all in-cab brake controllers) have to be mounted near that wiring in the front of the vehicle, underneath the dash. If you're okay with that, for…

I took a look at the owner's manual for the 2012 Jeep Grand Cherokee Laredo V6 3.6L. The 3.6L engine Grand Cherokee can tow a 5,000 lb trailer. That figure is the gross weight so that would include all of the cargo inside the trailer. You want to…

Answer 7

The brake controller you sent in a picture of will only affect the brakes of a trailer you would be towing. It does not affect the brakes of your vehicle in any way if you were to leave the controller installed. I attached an FAQ article on brake…

I found a copy of the owners manual for the 1999 Chevrolet S-10 truck and in the Recreational Towing section, Chevrolet says your 1999 S-10 should not be flat towed. They recommend towing it on a trailer only. If the vehicle absolutely must be flat…

I did some research and found that the manual for the 2000 Chevrolet S-10 pickup states that the vehicle is not to be flat-towed. The manual states that the transmission is not designed to allow it to be towed behind another vehicle. The suggestion…

Answer 10

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

Answer 11

The backing plate you are referring to is, I'm assuming, the brake mounting flange, which should be welded on. The dimensions of this are extremely important because it will determine the brake assemblies that fit. The Demco Trailer Brake…

Answer 12

Class I and Class II hitches both have a 1-1/4 inch receiver opening. The difference is that a Class I hitch has a lower tongue weight rating, usually 200 pounds and a lower towing rating, usually 2,000 pounds. A Class II hitch usually has a tongue…
