Trailer Light Wiring Question
« on: March 19, 2007, 10:35:35 am »
I need to re-wire my entire trailer for the rogers so I can drag it down to the DMV to get it registered.

I am looking at some LED light kits on eBay.....is there anything I should look for or stay away from?

Also, on my truck, it has the big round style plug, and I always have to use the 4 pin (3 males, 1 female) plug adapter.

Which plug should I wire my trailer with?

Is it possible to wire reverse (backup) lights on the trailer? or would I have to run an aditional plug?

L.E.D. lights are cool, shouldn't need to look for any red flags. They're brighter, last longer, won't mess with the turn signal flasher near as much, they're the way to go.

The big round trailer plugs are all wired the same (assuming it's wired at the factory) and I've included a pic in this post that show's what is where in that plug. The diagram is showing you the truck's side of the plug looking at the pins of the plug. You'll notice there is a reverse light wire in there already. So if you wire up your trailer using that big round plug you'll have your reverse light capability pretty easily.

The 4 pin plug is the most common. The pic of the 4 pin plug is the trailer side of that plug.

Trailer wires (never varies if factory wired, either style of plug):
White: ground
Brown: tailights
Green: Right turn signal/brake light
Yellow: Laft turn signal/brake lights

I recomend running all of the various light ground wires to the tongue of the trailer, grounding them all at the tongue in the same screw, and wiring up the trailer's plug's ground wire to that same screw so that they are all grounded at the exact same spot. I also recomend using a small bolt and nut for the ground wires vs. a self-tapping type of screw.

Hope I helped and let me know if I missed something/you have a question.

By the way, if you do wire up the trailer with the round style plug I recomend you make a jumper plug to go from round to 4 pin just in case you run into trouble some day and need your boat towed by someone else's truck.   :o

this is the exact reason why I carry a 4 pin to 5 pin adapter in my glove box. I will just pick up a 5 pin to 4 pin adapter and keep it with me as well.

...but what if my truck isnt present. ...hmm....ok, you got a point. you win.  ;)


so anyways, yes, the 5pin is factory wired. I guess I will just wire both a 5 and 4 pin on the trailer.

this is the kit I am looking to get: http://cgi.ebay.com/ebaymotors/Ultimate-Race-Boat-LED-Trailer-Light-Kit_W0QQcmdZViewItemQQcategoryZ50437QQitemZ4529753259QQrdZ1QQsspagenameZWD1V

5 pin   ???  I count 7 pins on one (round) and 4 pins on the other (flat), does your truck have 5? Maybe it has 5 pins in it but fits the 7 pin plug?   ???

If you're going to have reverse lights on the trailer I would wire up the trailer for the round plug and just use the pins that are needed on the trailer. Then I would make a short jumper (maybe a foot long) converting the trailer's round plug to the flat plug omitting the reverse light wire in that short jumper (for when someone else's truck needs to tow the trailer). I wouldn't wire the trailer up for both plugs because I would be concerned that if the unused plug happens to come loose driving down the road it may become damaged and create a short on the wires (then your fixing your lights on the side of the freeway, looking for band-aids to use for tape, people honking at you, making fuses out of tin foil, pulling the cords out of your tires to make wire, wait a minute I'm getting off track   ;D  ). If you do wire up the trailer yourself keep in mind you can always wrap any extra wire up around the trailer easier than you can make the trailer's wiring longer, better too long than too short.

I ahve no idea if the price is good but those are cool looking lights.   ;D

Oh yeah, I have been known to travel to do side jobs...

I once did a job for a guy where I wired up his utility trailer with its own special plug and made adaptors for that special plug to go to the round and flat style plugs. He was concerned about someone stealing his utility trailer. He just kept the adaptors with him whenever he wasn't around his trailer.  :o

So today I went down to Pep Boys to buy some stuff for Brad's boat trailer and I found out that there's a lot more different types of trailer plugs than I have see/thought.

There's a 7 pin round, 6 pin round, 6 pin rectangle, 5 pin round, and a 4 pin flat.

I'll bet each one of those inventor's has $1,000,000, unless they didn't patent their's. Only in America brother!   ;D

this is probibly too late,but i strongly rec. the flat four. everone's using it, the round 7 is factory installed on new trucks but also with the flat four. the olden day round 5 & 6 are out dated! plus if you rent a moving trailer, or help a friend move there trailer it WILL have a flat 4. so change your vehicle's plug to the flat four, you be happy you did.  O0 nice lighting kit on ebay

I hate the little flat four plugs, they look like shit just hanging there. I like the round plugs and have always used the ones that competitive trailers use, U-haul also carries the same exact one. I mount one in the trailer too, make up a nice little pig tail and keep it in the car. I can't stand wires hanging from the trailer either. The female end of the plug has always fit very nicely in the same hole that houses one of the license plate lights on the last 3 trucks/suburban that we've had. I don't like drilling un-necessary holes in my boats, or cars.   ;)

There is a definate advantage to having your tow vehicle equiped with the round 7, you'll always be able to tow any trailer you want to (electrically speaking).   ;)

I definitely have to agree witht hat one!  I have the round 7 on my truck and bought an adapter at Pep Boys that has both the flat 4 and flat 5 on it.   Pretty sure I can tow just about any modern trailer with it now!

Rod - I have a few things I need to get done on the boat!  I had the engine replaced last year, came back without the bilge working, tac no loger works.  I probably need to get it all working once I get the bowl back on it so I can put it on the water.  The boat is stored in Riverside, i can bring it to you if that works better.  Not sure what it will take to get it all done so I am not even gonna ask you a price right now.  I'm heading out of town until May 6th, maybe sometime in May if you want to take a look at it?

just for the record....we did end up putting a 7 pin on the trailer. I will eventually pick up a 7to4 adapter just in case someone with a 4pin needs to tow my boat for some reason.

and eventually, I will be putting a 7pin socket on the trailer and just have a jumper between the trailer and the truck....

the socket on the trailer will look something like this:



and the connector between the truck and trailer will look like this, but it will be 7 to 7



I think this will be a cleaner install.

Most boat trailers are wired up one of two ways, either a pair of wires running down each side of the trailer or 3 wires running down one side, around the back, and half way back up the other side of the trailer. Typically Brown wire is used for tailights/side marker lights. I have also seen it where there's two wires running down each side, one red and one black wire, in that case black is tailights/side marker lights.

Don't forget to check your underhood fuses too. I didn't realize I had popped one and redid the whole left side of the new trailer... The old trailer I guess had a short in it.
