Hello Ronald, thanks for reaching out. The best thing to do here will be to use the Hayes Air Actuated Trailer Brake Controller # HA100400C. This will allow you to control the electric brakes on your 5th wheel with your 2013 Peterbilt 337 day cab with air brakes.

You will also need to wire the Peterbilt with its own 7-way. For that use the Curt Powered Tail Light Converter # C59236 and the Universal Installation Kit # ETBC7. This will have everything you need to wire a 7-way. This kit comes with 25' of wire, so for a semi you may need some additional 10 gauge wire part # 10-2-1 to complete your installation.

Ok, so we do have a really good option for your 1991 F-350, and since you don't want a proportional brake controller that activates based on your truck's deceleration, what you will need is a time-delayed brake controller. What a time-delayed…

The trailer connector used on most semi-tractors is a 7-pin round which is similar to a 7-way flat used on most RV's but the big difference between them is how the stop and turn signals are wired. The stop and turn signal circuits are separate on…

Answer 7

Either way is correct. It depends on if you want to keep the semi-style 7-Way (if you need to tow that type of trailer) or if you will never be towing a semi-trailer. If you need to keep the 7-Way semi active on the truck, then you would need to make…
