Expert Answers about 3M

  • Wiring a Side Marker Light to the Running Light Wire on a Trailer
  • You can run a jumper wire to T-off from the main running light wire to the side marker light using something like a quick splice connector, # 562. Or you can use a butt connector, # 05732-2. In one end, place the wire from the trailer connector and in the other end insert the wire from the side marker light and the wire to the tail light. You would need to cut the brown wire at some point to wire it in this manner. And yet another option is to run the side marker wire all the way...

  • New Trailer Wiring, Connector, Junction Box, and Battery Box for a Trailer
  • We have 7-wire strands but no 5-wire. What I recommend is to use duplex wire # 10-2-1, sold by the foot, for the brakes and bonded 4-wire, # 16-4B-1, also sold by the foot, for the lighting functions. For a junction box you can use # 38656. I have linked a couple of videos showing installations featuring these products for you. For a 7-Way trailer side connector you can use # H20046 with the wiring listed above. For the junction box you will also need some ring terminals. For the trailer...

  • Replacing 5-Pole Trailer Connector with Unusual Number Of Wires on Boat Trailer
  • Are you speaking of a 5-pole flat connector like part # 20017? Your description of the plug itself seems to match, but the number of wires on each pin sounds pretty unusual. I've provided a diagram of the usual wire functions on a 5-pole. As you can see, there's nothing unusual about the right turn, left turn and the two wires for the running lights on the driver's and passenger side of the trailer. Having more than one ground wire or more than one wire for the brake solenoid is...

  • New Side Marker trailer Lights are Very Dim
  • It sounds like a bad ground connection. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. But can also appear when changing out lights. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds...

  • Are The 3M Scotchlok Quick Splice Connectors Weather/Water Proof?
  • The 3M SCOTCHLOK Quick Splice Wire Connector - Blue Gel - 14-18 AWG (Qty 1) # 804C is weather proof and water tight, but not waterproof. The connector is filled with a weather protecting gel similar to a dielectric grease that protects the splice from water and debris. As long as the gel remains as a protective layer, you won't have issues.

  • Quick Splice Connector Recommendation for Tapping into Stoplight Switch Circuit
  • We don't have that info but I would almost guarantee it's a 16 gauge wire. The good news is that the part # 804C is a quick splice that fits gauges between 14 and 18 so it should work the best.

  • Availability of 3M Quick Splice that is Same as 560B-BOX
  • Actually for a quick splice that is more like the 560B-BOX that you have you would want the part # 564 as it has the exact same shape but is just different colored. The part # 804C would still work for you but it is a different style.
