Trying to hook up a 98 Disco to a trailer we recently bought. It came with a hitch but from what I can tell there is absolutely no wiring to speak of, does anyone know what needs to be done? Are we talking about splicing the wires going to the brake lights? Could anyone give me a rundown of what needs to be done? Thanks in advance,

All LR's come from the factory with a trailer hitch but no wireing.
There is a "plug-N-play" wire harness from www.atlanticbritish.com, that is what I did. I will not cut wires.
It is alittle pricy but it works great. You might find one cheaper somewhere else but I couldnt.
And remember that because you have seperate turn/stop lights that the plug-n-play harness is not a standard one. The standard one that you can get at a trailer shop will not work with seperate stop/turn bulbs.

My suggestion would be to get the factory harness from Atlantic British or another source if you find it cheaper. If you don't want to spend that kind of money you can get a tail light converter and that will match your turn signals and brake lights to your trailer but you will have to splice wires. What kind of plug does your trailer have? Is it a 4-flat or 7-round plug?

 

I was led to believe the OME from LR terminated in 7pin "hard mount" on the bumper & then had a pigtail that converted to 4pin. So, since I am so smart and wanted to try to stay original equip, I ended up with $240 for the wiring & $285 in labor to end up with a 4pin pigtail attached with plastic ties to the hitch. I guess the stop/tial lights is part of the cost. Does that mean the 4pin will work the boat stop/turn lights correctly? I haven't had a chance to check yet.

By the way - Spike555, the suggestions and help on the overheating worked - THANKS.

 

My '97 came without any trailer wireing, so the 7 round that you are talking about must have been dealer added.
Yes, with the correct wiring convertor the stop/turn lights on your trailer will work correctly. Without the correct wiring convertor they will not work correctly unless you cut the right wires.
I have found it is always best to spend the money and buy the plug-n-play convertor.

 

Thanks for your responses, I'm a wiring guy and through trial and error could probably figure it out. Does anyone have a link for which wires to splice as well as a pinout for the 4 flat connector.

 

You will never get it to work right. The truck has seperate stop/turn bulbs which means that they are each on different circuits. Your trailer has a single stop/turn bulb.
You will be cutting up your wiring for nothing, it will never work. You are just creating trouble for yourself that you dont want.
Bite the bullet and buy the plug N play kit from www.atlanticbritish.com or other place thatcarries it.
Do yourself a huge favor and buy the kit. 10 min install.

 

Spike everything you have told me up to this point has been dead on, so I'll take your word for it.

Once I buy the kit does it have easy to follow instructions or does someone need to tell me on here how to do it.

Also, do any chain places ie AutoZone, Napa, Advance or do you have to order it online?

As always thanks for the help.

 

The one from AtlanticBritish comes with easy to follow directions. They have you run the plug through a gromit in the floor, I didnt do this, I left the plug inside the cargo area and just run it out the back door when needed making sure not to cut it with the door slide.

I could not find one anywhere other than on-line. I made sure that I bought the kit that just plugs in, no wire cutting at all.
I bought mine from www.atlanticbritish.com. Very pleased with it.

 

I bought my converter from Agrisupply (ASC) for $12.95, a converter and four prong connector built in one. It comes with ScotchLocks to splice (no cutting) into the truck's wiring. I've used it for several hundred miles so far, no problems.
