Need answer on trailer wiring

[Stumpknocker]

Ok, the little blue thing that folds over and has an aluminum blade that sinks its teeth into the wires.... (they are junk) anyway if you are wiring up a side marker light, and need to attach the brown wire to the existing brown ground wire running along the trailer.... whats the best way to do this? Three way connector made for this? A triple solder? If you solder... how do you heat shrink a three way? Questions questions....<br /><br />Somebody edumacate me please....

Yes those self taps are junk but toss a few in the glove box just for an emergency repair.<br /><br />You can ground your trailer ground wire to any metal part. I have used self tap sheet metal screws. If you ground it seperately you will not interfere with the integrity of the exsisting wire. <br /><br />The only reason you would shrink wrap a ground is to keep it away from corrosion. Actually a clean soldered ground can be left exposed.... it will not short anything.<br /><br />Bob

If you are talking about the brown wire for the marker lights. That is not a ground wire that is the tail light and marker light wires.<br />I just skin some of the insulation back and wrap the leading end from the marker light around it and soilder it good and then put liquid tape on it and then wrap with good black tape.

If you solder... how do you heat shrink a three way?

Use heat shrink tubing just large enough to go over two wires. Put the tubing over two of the wires nd then twist all three together so the two with the tubing are going one way and the other is exiting the splice the other way. Solder the connection, push the tubing forward over the joint and heat shrink it. Or, twist all three together, solder, and then put tubing over the joint and shrink it. You'll need to seal the end with liquid tape. You can also get crimp splices meant for reducing wire sizes (12 >14, etc.) Put two wires in one end, the remaing wire in the other end, and crimp.
