Question:

Good morning to all! I am replacing virtualy all equipment on my 1984 Shoreline 25 ft boat trailer. It has 3500 pound tandem axles and hauls my 1984 Chapparal 235XLC 4500 lbs I have already received my first order $820 and was 100 complete! I have determined I will convert from Hydraulic to electric brakes. I am ordering parts #23-469 rh, 23-468 lh, 84546uc3. I have checked my old bearing numbers and they match the ones supplied in the above parts. I am ordering all nuts and lock washers and stainless bearing buddies to complete the wheel refit. These will be outfitted with the Dexstar Galvanized mini mod wheels I have received already. The trailer had brakes on the back axle only with just hubs on the front axle. I have both axles down to the spindles and can go either new brakes on 4 wheels or just the two rear wheels. What is your recommendation. 2 or 4 ? I have purchased an AREO PROLCD light kit #TLL36RK that has the wiring with it. Will I only need the 2 wire for the brakes PART # DEKA 10-2-1 and then wire all wires from them into a new 7 wire plug to fit my factory installed 7 pin socket on my 2002 F150 with trailer towing package. I am ordering the Tekonsha Primus IQ and the plug in adapter for the connection under the dash. Thanks for all your help!

Thanks for your recent purchases and sending us a picture!

It's always better to add electric brakes on both axles because it reduces the stress on all components.

You will need a 7-way molded connector # H20046 for your trailer to plug into your 2002 Ford F-150's 7-way connector. This connector is 8 feet long.

I highly recommend getting a junction box like # 38656 or # PK52248 because it's an easy way to connect the wires from trailer connector to wiring for 6- or 7- connectors. It also makes it simple to replace or troubleshoot wiring connections.

Take a look at the informative articles and videos I included for you.
