Two Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights - A68P

Average Customer Rating:  4.8 out of 5 stars   (18 Customer Reviews)


This connector is too bulky to be used against a standard clearance light bracket. It will not fit. It is however a nice weatherproof connector, it just won't work with any similar setup like mine (pictured below) which seems to be pretty standard.


Perfect replacement part.


Here is a picture of these in use on the front of my truck, its an unorthodox mounting place and its supposed to be used on a trailer but I really love these things and I have installed them onto another guys truck as well


Great product and easy to install with my new LED side Markers!


Fast shipping and high quality products. Worked well and easy to install. The detailed photos really helped to find the right product. Unlike other online retailers who's photos don't do the products justice. Thanks


My trailer (like most trailers) came with single wire sockets & ground connection through screw into frame. However, ground screws are subject to corrosion which causes intermittent connection - lights sometimes don't work, or are dim. Using these 2-wire connectors & a real wire for the ground side eliminates this problem. A little bit of work to run new ground wire, but well worth it. Product shipped & arrived quickly. Thank you!


purchased these plug and mounting covers with the lites. will be using them on my 28ft in closed trailer as rear marker lites over the door. very impressed on how bright they are and the great price.when putting them togather its just a snap. would advise my friend to get them.


I ordered these to replace the ones on my trailer that weren't working. They were easy to install and light up great.


While etrailer's products have been good so far (I have ordered several items lately), what really pleases is their quick and pleasant service. Always easy to deal with, and that makes a difference.


Positive: Nice slim line profile.
its wires come out to the side and are difficult to mount if the trailer opening for the light is directly behind the light fixture.


The product worked as it was intended. The service was great and the item arrived quickly.


Very happy with the quality of this product.


These were just right for my needs, and the online ordering and delivery system are first class. Thanks!


Part was exactly what I needed. Extremely fast shipping and great customer service!!!

  • Can You Tell Which is Ground and Hot Wire on Two Wire Plug A68P
    There is not a way to tell beforehand which of the wires is for ground and which is the power wire for the Two Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights # A68P. Like you mentioned, once it is hooked up you will be able to tell but there is not a way to do so beforehand, so it will simply take (a small amount) of trial and error. That said, if your trailer has two wires you are connecting then the one attached to the frame is going to be the ground.

  • Will Thin Line Clearance Light # MCL63AB Work with a Mounting Bracket # A67CB on Aluminum Trailer
    Yes, the Chrome Mounting Bracket # A67CB that you referenced will work on your aluminum trailer with the Clearance Light # MCL63AB, but since you have an aluminum trailer and the bracket grounds through the mounting hardware you will also need a Two Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights # A68P.

  • Mounting Bracket Recommend for Running Power and Ground Individually to Thin Line Clearance Lights
    To use the # MCL63RB and run the ground and power wires directly to it you would need the part # A68P as well. This would allow you to wire up the light without having to ground the light through the mounting hardware. For a bracket you would then want the part # A65B.

  • How is Sealed, Miro-Flex, Thin Line, LED Trailer Marker/Clearance/ID Light, # 12855, Wired
    Sealed, Miro-Flex, Thin Line, LED Trailer Marker/Clearance/ID Light, # 12855, requires a bracket to mount the light. The light itself can plug into the bracket and ground through the mounting hardware.

If you are unable to ground the light through mounting hardware, you can use Two Wire Plug for Thin Line Series Trailer Clearance and Side Marker Lights, # A68P....

  • Mounting Base and Wiring Harness for Optronics Clearance Light # MCL63CAB
    There are different bases you can use for clearance light # MCL63CAB. You can use base # A65B that you have referenced. For that particular base you would use wiring harness # A68P. We also have base # A65PB or # A66PB. With these you would use wiring harness # A65P with the single wire because the light will ground through the mounting studs of these bases.

  • Recommended Trailer LED Taillights for a 1961 Airstream Camper
    The fact that your trailer uses single wire assemblies for the running lights indicates that the assemblies are intended to ground through the mounting hardware. Which is interesting since the trailer is aluminum. For red surface mounted LED clearance lights the part # MCL63CRB that you referenced would work well, for the amber version part # MCL63CAB. For an install plug you would want part # A68P and then for a bracket part # A65B. Or for an entire kit that comes with everything you...
