Parts Needed to Add Back Up Lights & 7-Way Connector on Boat Trailer

Question

Question:

want to add backup up lights to a boat trailer the trailer has a 4 pin harness I think I will have to run a new wire for the back up lights and then since my tow vehicle has a 4 way and a 7 way I figured I would switch the trailer from 4 to 7 so when tow vehicle is in reverse the new back up lights would come on sound correct? if so do you carry what I would need including the submersible lights 2014 Jeep grand Cherokee

We can get you set up to add back up lights and a 7-way to your boat trailer, and I'll go over what you'll need. Let's start with the back up lights, and for your boat trailer you'll want submersible lights like you said, the GloLight LED Backup Light for Truck or Trailer - Submersible # BUL111CFPG.

This will use a 2-wire (power and ground) pigtail, either the Right Angle 2-Wire Pigtail # A49PB or 2-Wire Pigtail # A45CB.

Then for added wire I recommend 16 Gauge # 16-1-1, which is sold by the foot, and for a trailer side 7-way, if you want a junction box you can use the Junction Box # 3375601100, 7-Way Connector # H20046, and Ring Terminals # 44-5310A.

I have added links below to video reviews for you to check out as well if you'd like.

Answer 4

An EZ lube spindle will be better because it allows you to insert grease from inside the spindle where the bearings are and push out the old grease whereas with a Bearing Buddy you basically just get to push grease through the front of the hub. I…

For most RVs greased hubs are a better option than oil bath hubs, and for the exact reason you mention. While it is obviously not good to run your greased hubs without a full load of grease, this tends not to result in catastrophic failures, mostly…

The Curt Echo Wireless Trailer Brake Controller part #C51180 is what I recommend for a 2016 Volvo XC90. In regards to sync/setup, this is super easy and only needs to be done once per trailer. Once synced, it simply plugs in and you are ready to go.…

Answer 11

The grease in your bearings can break down over time so it is best practice to repack your bearings every 12 months (or 12,000 miles but this doesn't apply to you). Now, if you were to accidentally forget to repack them one season it wouldn't…
