A friend of mine recently purchased some running lights for the running boards on his truck! Each light has a black wire that goes goes into a 2-hole connector. Inside the other hole of the connector is a white wire which also came with the kit that runs through each connector of each light! Each connector has a metal pin that pierces into the wires...

My question is: At the back of the truck there is two different trailer plugs. One is a 6 prong plug and the other is a 4 prong plug. We were thinking of putting a connector at the end of the white wire that came with the lights and a wire that is connected to the plug, will this work provided we connect it to the correct wire at the plug?

I would post a pic but I cant post attachments!

TIA

 

Yeah, that'll work.

I know Ford pulls the 4 flat from it's 7 pin. Just check the lines before you splice in and see what's what. You'll only need 12volts to fire off the lights, so a ground and the running light line would be perfect.

 

Ok, great! Since we are using those 2 hole connectors to splice into the wires, we will also have another wire from the opposite side of the truck coming from the other set of running lights going to the same wire on the plug...Do we just pierce into the 4 prong plug wire in a different spot using the 2 hole connector like before?

 

Sure...

If it were me I'd ground the lights to the chassis at the closest reasonable point, then just run the positive lines to the tail light wire that feeds your trailer plug. You didn't mention what make/model truck your working with so not positive which color feeds your plug. Decent shop manual will show though.

Either scotch lock the positive leads from you running lights to your harness or make a junction. Fewer splices will make for easier troubleshooting in the future so keep it simple.

 

The truck is a 2001 Ford F-250!

Scotch locks is what we are using (I was calling them 2 hole connectors
)

Since there is just 1 wire coming from the running lights on each side, how would you ground them exactly? Sorry for my ignorance on the subject!

 

If there's just one wire, they probably ground through the metal running board to the truck frame. I had some really old ones that did that; perhaps they still make them that way.

 

Yep, come to think of it thats how it was done! Thanx for the input!!
