Worked very well with the 1/4" metal loom clamp, item #A0250 to keep the power wire for the Tow Ready Trailer Wiring in place and away from moving parts



by:

This was recommended in another comment by an etrailer employee to use to attach part # BK70BB - Trailer Light Mounting Bracket to the curt cargo carrier. These screws were way too small for that usage. I ended up using some 1/4 inch self-drilling screws that I had and added these to my stash.

I agree with Rick, these screws DO NOT fit part BK70BB - Trailer Light Mounting Bracket



by:

Products arrived quickly and were exactly what we ordered for rewiring our trailer as follows: 35 ft 4-way trailer wiring harness with 42" ground wire; metal loom clamps; wire loom and hex screws with wash heads. This company has a very good selection with good prices and economy shipping.

My brother and I purchased suspension parts, brake kits, wiring kit, led lights and other accessories for are car trailer. Great products, will by from etrailer again.

These screws were recommended by etrailer and worked perfectly for mounting hose clamps on the underbody of our minivan!

Ordered several towing and cargo products for a pending trip in 4 days! Great communication from the eTrailer team (George and Jamie) on delivery dates, etc. One product was not available in the warehouse, but eTrailer contacted the mfr and had them drop ship with express delivery to meet my timing needs. Really no effort on my part to get this great service -- just seems to be the way they operate. I keep ordering from them, and they keep exceeding expectations. Way to go! A+++

  • Best Way To Attach Trailer Plug Bracket To A Trailer Hitch Without A Pre Welded Bracket
    As far as the mounting bracket, you can absolutely screw it directly to the hitch if you want. We do this frequently in our own installs and it will not compromise the strength of the hitch in any way. Now putting a few holes in the hitch does open up the potential for rust, since we are compromising the powder coating, but the risk is small. You could use the bracket # BK4F for a 4-flat or use the # C67UR for a 7 way, and a self tapping screw like # 101131802. If you do not want to drill...

  • 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 Do I Re-Wire My Pop-Up Trailer To A 4-Pole Trailer Connector? They
    In order to wire your pop-up trailer with a 4-pole wiring harness like the 35 Ft 4-Way Trailer Wiring Harness - Wishbone Style # A35W42B, you're going to first have to: 1. Connect the white ground wire to your trailer's frame. You'll want to make sure that the spot you choose for grounding is a clean, bare, surface that is free from rust. You'll use the already attached ring terminal, as well as a self-tapping screw # 101131802. Before you secure your ground wire, be sure to leave the...

  • Will the 1/2 Inch Metal Loom Clamps Work On a 5/16 Inch Frame Rail
    Yes, the Metal Loom Clamp part # A0500 will work on a trailer frame that is 5/16" thick. The Metal Loom Clamp will actually work on pretty much any frame thickness but you will need to make note of the size screw used. I recommend the Hex Screw part # 101131802 for a 5/16" thick frame as it is 1/2" long. The Wire Loom part # 459075 can then be added to protect your wiring. I have attached a list of our other wiring accessories for you below as well.

  • Dragon's Eye LED Clearance or Side Marker Light Colors and Mounting Hardware
    Yes, the Dragon's Eye LED Clearance or Side Marker Light is available in Amber # DG52440VP as well as Red # DG52441VP. When we installed this on a trailer we used the #8 x 1/2" Hex Screw # 101131802 which is great for metal installations. If you'll be installing these on a different type of surface you'll need to use the appropriate screw type.

  • Does LED Trailer Fender Clearance Light Need a Ground Wire That Goes to Wiring Box?
    You do not have to connect the ground wire of the LED Trailer Fender Clearance Light # MCL180ARB to your main ground that goes to the wiring box. What you can do is use a ring terminal such as # 44-5310A and screw like # 101131802 and ground it to your trailer frame close to where the light is.

  • Hardware Needed to Install Optronics Thin Line Fender Trailer Light
    There isn't a specific hardware kit for the Optronics Thin Line Fender Trailer Lights # BA65ARRB for the right and # BA65ARLB for the left. I contacted Optronics and they told me a number 6 sized screw like part # 1172904 or a number 8 sized like part # 101131802 will fit.

  • Brake Controller and Plug and Play Harness for 2018 Toyota Tacoma With Factory Tow Package
    The Prodigy P3 # 90195 will work with your 2018 Toyota Tacoma's factory 7-way with Wiring Adapter # 3031-P. All you need to do is plug one end into the P3 and the other end into the port underneath your Tacoma's dash; you will need to ground the white wire of the adapter to a bare metal surface using a self-tapping screw such as # 101131802.

  • Right Hand Tail Light Goes Out When Vehicles Headlights Are On
    I am assuming that you mean the right hand trailer tail light goes out when you turn the headlights on in the vehicle. If that is the case then this sounds like a ground issue. In order to remedy this you are going to need to reground each tail light assembly and both the vehicle side and trailer side trailer connectors. The tail light assemblies will ground via a single wire or the mounting hardware. If they ground with a single wire then you will want to remove the wire, sand down the...

  • Replacement Trailer Lights for Shorelandr Boat Trailer
    The Optronics Tall Rectangle Submersible LED Trailer Tail Light, part # STL56RB, should work on your Shoreland'r trailer. The same light for the left side of the trailer is the Optronics Submersible LED Trailer Tail Light, part # STL57RB. We have gotten back many reviews of these lights working just fine on Shoreland'r trailers. I will give you the dimensions of the lights so you can make sure they will fit your trailer. The light is 6-1/16 inches long x 3-5/8 inches wide x 2-1/4 inches...

  • 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...

  • 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. Mounting bolts are included but nuts and lock washers # BRKH10B are not. If it were me I would purchase the etrailer # AKEBRK-35-SA self adjusting brakes so that I would...

  • Plug-In Brake Controller Harness for a 2018 Toyota Tacoma
    Yes, the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers part # 3031-P is a plug and play harness that will allow you to install the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 on your 2018 Toyota Tacoma without any cutting or splicing. You will however need to ground the white wire to a bare metal surface with a self-tapping screw like part # 101131802.

  • Recommended Self-Tapping Mounting Screw for Hopkins Bubble Level Mounting on Fiberglass Camper Shell
    The Hopkins Never Fade Trailer Bubble Level Set - Graduated - Two Way - Stick On/Screw On # HM08526 you referenced does not come with mounting screws. I recommend using the Hex Screw - Self Drilling Unslotted Washer Head # 101131802 for your fiberglass camper installation. Be careful not to over tighten or they may damage your camper or level.

  • 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...

  • 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. The red wire you mention is for the reverse lockout on the trailer coupler, and is tied in with the reverse lamp circuit of the vehicle. Both brown wires would connect to the brown wire of the trailer connector. The yellow and green...

  • 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...

  • Locating the CHMSL and Interior Light Wire to Wire SnugTop Shell on 2000 Chevrolet Silverado
    I can help you wire up your SnugTop Shell to your Silverado but there are no direct connectors to do this, you will have to hardwire it into your vehicles lighting circuits. There are a couple of places you can access a dedicated brake light only circuit on your 2000 Chevy Silverado. First, you can tap into the circuit behind the third brake light on the cab of the truck. The brake light wire might also be located in the back of the vehicle. Some Silverado trucks come with the brake light...

  • Replacement Self-Tapping Screw for Ground on 4-Way Wiring Kit for 2011 Dodge Grand Caravan
    To replace the self-tapping screw used for the ground wire with the T-One Wiring Kit # C56331 you'll need part # 101131802. Be sure to use a 3/32" drill bit to drill out a starter hole prior to installing the screw.

  • Can You Use The Frame For a Ground When Using 4-Way Harness With Full Length Ground Wires?
    You are correct. You can cut the ground wire and attach it at the front of the frame using a Ring Terminal # DW05737-1 and Self Drilling Screw # 101131802. Be sure to sand the frame to bare metal here and where you make your light connections to ground. Then you will want to spray paint over the top of the connections to reduce corrosion to the bare steel.

  • 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...
