You have it right so far, the 4-way connector is just as you have stated. Remember that Yellow has a L in it so that is the left side brake/turn signal and green has a R in it so that is the right side brake/turn signal. The colors for wiring a 7-way…

For U-bolts for your 3" x 3" frame you will want something that is slightly larger. If the measurements were listed as exactly 3" it isn't going to fit. What you need is the CE Smith U-Bolts - Galvanized - 3-13/16" Long x…

For new 5-way wiring what you'll need is the part #A40W5B. This will handle all of the wiring that runs from the connector back to the lighting assemblies as well as for a reverse lock out solenoid. Surge brakes don't always require wiring as…

The Demco Hydraulic Brake Actuator part #DM72VR is a great option to replace an Atwood 82543. That said, it does not come with any sort of reverse lockout feature therefore in order to reverse without the brakes locking up you will either need to add…

Hi Gary; you're referring to the Hydrapro Alpha G-1600 #DH94FR. Most states require a separate battery by law so it is best to install a breakaway kit like the #3802308. This ensures the breakaway will work all the time since the coach batteries…

For a replacement 5-way we have the Hopkins 5-Way part #HM47913 which will work great. This even has circuit testers for each wire so that you can easily make sure everything is working properly. Wiring configuration on #HM47913: Green: right turn…
