Trailer Wiring Diagram

[sstone]

Anybody have a link for a basic wiring diagram for a boat trailer? Trying to fix some jury rigged wiring on an old trailer and need something to go by. The trailer has one amber light on either side, brake light/tail light combos, and a light bar in the middle of the back. Also, its a 4 pin connector, with 5 wires coming out of it. And the one coming off the connector that is different than the other three doesn't seem to be connected to anything, yet the left side lights work completely normal. The right sides don't.

Re: Trailer Wiring Diagram

Perfect diagram. The wire is white, the ground wire. I know where the right sides aren't connecting, rotten connector and a split wire midway through the trailer. What's the best connector for the split at the amber lights? Also where does the trailer ground connect, anywhere on the tongue?
I'm pretty clueless with wiring

Re: Trailer Wiring Diagram

Yes you can connect the ground anywhere on the tongue. Just make sure it's not in the way. Most people use the ones int photo. But I like the ones in the link and last photo better. They have a moister control in them. Read info for the details. It says to use soild wire, but I just stripe the end of the wire & twist it & than solder it. Works great. But in the photo you can see that its stranded wire. So you don't need to solder it. If you don't want to. It works the both ways.

Thanks for the help. It's stranded wire and I don't have any solder equipment so I'll go for the connectors.

Re: Trailer Wiring Diagram

When you are splicing your wires I highly suggest you use heat shrinkable splices similar to these at Lowes http://www.lowes.com/pd_123065-1270...uctId=3127655&Ns=p_product_qty_sales_dollar|1 You will need pinks for what you are doing except when you splice two wires into one and then you will need blues
