Question:
Hello Conner, this morning I purchased the Hydrastar Disc Brake conversion kit (Part # HSE7K-T1 - Order # 123493325), for my 2008 Jayco Octane ZX 29 foot toy hauler with tandem/dual Dexter 7K axles. My tow vehicle is a 2005 Suburban 2500 with a Tekonsha Primus In Porportional Brake Controller. Double checking that this kit is the correct kit for my Dexter 7K axels. Is there anything the kit doesn’t include that I will need for my tow package? I read somewhere that I may need a circuit breaker? Thanks for your help. Bill

Hey Bill! The Hydrastar Disc Brake Kit w/ Actuator for Tandem Axle Trailers # HSE7K-T1 will fit the Dexter 7k axles on your Jayco. If you look at the wiring diagram below it does call for a 40 amp breaker like the # PK54540. It is also worth mentioning that the Primus is only compatible with electric brakes. I recommend upgrading to the Tekonsha Prodigy P2 # 90885 or P3 # 90195 which are electric-over-hydraulic compatible. Both will connect to your existing wiring harness for a simple swap.

I’ve added those items to my cart. Would my existing Tekonsha Primus IQ vehicle specific adaptor also work on the Tekonsha P2? Thanks for all your advice.
