• Recommended Mounting Hardware For The Optronics Clearance Lights MC44AB1
  For mounting a clearance light I recommend using a few self tapping screws. Preferably a # 10 or # 8 screw like the # 101131802. You will also want some butyl tape # QR59FR, to weatherproof the screw holes. Hardware for these is basically generic and it really comes down to what surface you are mounting to. Optronics does not sell a hardware kit specifically for the # MCL44AB1 or # MCL44RB1.

• How to Wire a Trailer for Tail Lights
  First, lets make sure you have all of the parts you need to wire a trailer for lights. If you have an old trailer and want to replace everything, I recommend using a kit like our Optronics Tail Light Kit, # TL29BK and our trailer wiring installation kit # HM51020. We also have an LED kit, # TLL9RK. Step 1 - The trailer connector should extend 2 - 3 feet past the tongue. Attach the ground wire directly to the tongue of the trailer using a self tapping screw # 101131802 and a ring terminal...

• Why Do Trailer Lights Flicker When Hitting Bumps
  In order to fix the issue with your lights flickering you will want to pick a good spot on the trailer frame near the coupler and then run a ground wire from each of the lights as well as the trailer connector to this point. If you need to extend the wires you can use part # DW02359-1 and part # DW05744-5. Once you find a good ground point, sand the surface down, twist the wires together after you have removed part of the jacket, and then attach it to the sanded surface with part # DW05741-1...

• Recommended Trailer Wiring For 1995 Ranger 690T Boat Trailer
  I did some research and found that your boat is 18-ft 9-inches long. You did not say if your trailer has brakes included which will make a difference when installing the wiring. If you do not have brakes on the trailer and you only need wiring for the lights I recommend part # A35W42B. This is a 35-ft long harness and it has a 4-way flat trailer connector included. This is a wishbone harness that means the running light is split at the connector and the brown running light wire is run...

• Installing Electric Brakes on a Vehicle Tow Dolly
  You have a 3500 pound axle, with a 4-bolt axle flange, spaced 4” apart each. You also have tires and wheels with a 5 on 4.5 bolt pattern. To put brakes on your West Texas Dolly # WTD-35D you will need a left and right trailer brake kit like the etrailer # AKEBRK-35 rated for 3,500 pounds, and 10” x 2-1/4” brake pads.

• Installing a Brake Controller in 2001 Toyota Tacoma
  Based on my research, the 2001 Toyota Tacoma did not come with a factory trailer connector. However, since you already have a 4-way connector installed on your truck, you will be able to start here for your brake controller installation. I recommend the Tekonsha Prodigy P2 Trailer Brake Controller # 90885. This is a proportional brake controller with a digital display. It will level automatically when mounted within a 360-degree vertical range. The brake controller installs in your Tacoma...

• How to Connect the Ground Wire on a 4-Way Flat Wiring Harness
  The Hopkins Endurance 4-way Flat Trailer End Connector, # HM48110, that you referenced is the harness that goes on a trailer, not a vehicle. The 4-way connector for your vehicle is the Hopkins Endurance 4-Way Flat Vehicle End Connector, # HM48030. You can connect the white ground wire from the wiring harness to a vehicle ground, but you should verify that the white wire on your vehicle is in fact a ground wire. In most cases the white wire from the wiring harness is attached to a clean,...

• Wiring Replacement 5-Pole Trailer Connector on 2012 Ranger Trailer
  You can use a standard 5-pole trailer connector, you'll just need to wire it a certain way. The # HM47900 you referenced is the vehicle side connector, you need the trailer side connector like part # HM47910, which would wire as shown in the provided photo.

Both brown wires would connect to the brown wire of the trailer connector. The yellow and green...

• Lights And Accessories for Using Curt # C18153 Cargo Carrier on 2014 Chevy Suburban
  The only difference between the two anti-rattle hitch locks you referenced is that the # 63232 is for 2 inch receivers and the # SHP2040-XL is for 2-1/2 inch receivers. Since your Suburban has the 2 inch receiver, you'd need the # 63232. If the 4 pole on your Suburban is fixed in place on the bumper, I'd recommend the # 9653P extension. The Curt # C18151 you're referring to isn't specifically designed for a light kit, so they're aren't any pre-drilled holes on the carrier to mount a taillight...

• Can 2 LED Domed Utility/Multipurpose Lights Light Up a 24 Foot Box Truck
  The utility light # ILL24CB has 36 diodes so it will be on the bright side. Two of them will probably provide a decent amount of light but 3 would be better especially if light is essential. Attaching the lights to the ceiling using a high grade automotive type of double-sided tape would suffice. What I recommend is to use self-taping screws, like # 101131802, so you will not have to drill and then just seal the holes with a sealant like # 0160297. It would be best to attach screws to...

• Can a Trailer with Hydraulic Brakes Have Electric Brakes Installed
  It's actually not too difficult to swap out your hydraulic brakes with electric brakes. The main thing will be that you will remove the hubs of your trailer so that you can unbolt the assemblies and then reinstall electric ones. Beyond that you would then wire the assemblies up to the brake output circuit on your trailer wiring. You will want to measure your assemblies like in the photo I attached so that you can pick out the correct replacement to fit your hub. You will need to run wiring...

• LED Tailgate Light Bar Only Works Without Taillights On
  I am sorry to hear about the issue you are having with your light bar. The problem you described sounds like a ground issue. If you have a light bar that plugs directly into a 4-way then I would remove the ground from the 4-way and then attach it directly to a bare metal surface on the vehicle with a ring terminal part # 44-5310A and self-tapping screw part # 101131802. The majority of issues like what you described are caused by a bad ground as the circuit cannot handle the extra load...

• Cost Effective Wiring To Install 7-Way For Curt Echo Controller on 2008 BMW X5 With Battery in Trunk
  The Curt Trailer Connector Adapter part # C57672 can certainly be used to install a 7-Way on the 2008 BMW X5 to use the Curt Echo Wireless Brake Controller part # C51180 instead of the kit part #ETBC7L. I recommend to use the Curt trailer connector part # C57672 and the Power Wire Kit for Electric Trailer Brake Controllers part # BRK-ELECKIT because it has a shorter amount (10 feet) of 12 gauge wire since your battery is in rear cargo area. This kit also comes with all of the components...
