I have used my tacoma to pull my boat quite a bit here in my local areas,as well as my old truck(ranger) all of which I did not have great success with lighting that I get on my trailer. Have had only lights working when the headlamps are on or the parking lights. That was not really a big problem whenthe furtest I travel wit the boat is 30 miles maybe but now I am going to Santee Cooper from Virginia Beach in mid April and would like to get it right. The hitch is from U-Haul,the wiring is too. The connection is a 4 pin flat I am pretty sure from the hitch to the trailer. Back when the wiring and hitch was installed I thought nothin of it cuz all I wanted to do was go fishin since I waited the manual stated break in period to tow. I asked my stepdad who is good with automotive things and he said he thinks it is the amber turn signal,brake light combonation my toyota and previous ranger had. So I looked around the net and could not be positive on any product for my application. I am hoping some one can lead me in the right direction. The trailer is a jon boat trailer that holds a 14' jon setup real nice.

I work at a Larger RV Dealership, and we fix a lot of "U-Haul" wiring. Your Tacome requires a "Modulite tail light convertor" to process the three wire system of your truck, down to a 2 wire system for your trailer (per tailight).
To check your vehicle plug, get a test light, and the wiring code for a flat four is:
Green wire-Right turn
Brown wire- Running lights
Yellow wire_ Left turn
White wire- Ground

If those are not working correctly at your trucks plug, it's either not wired correctly, or you have a bad tailight convertor.

Thanks man. The lighting on my ranger was this way too so I think that I probably needed that Modulite thing on it too if not a bunch of other stuff too. Do you think I can find this locally and do you know if there is a special model for my truck? If I had a bad taillight converter would it affect the trucks lights while not hooked up?
Sorry about more questions but who here does not have questions.

It can affect the lights on your truck when not hooked up to a trailer, because it's the same circuit as your trucks lights on Tacoma's. Some of the full size trucks run a separate circuit for the trailer lights, but not Tacoma's.
When a tailight convertor goes bad, it can do all sorts of weird things to your lights.
You should try a RV dealer or Hitch shop for replacement parts. U-Haul can do it too, but your already in that mess.....lol
We charge $50.00 + parts to do a fresh install at our Dealership, to give you an idea of what it would cost to have someone else fix it. You'd be under $100.00 to rip out your old stuff and install new.

Alright. I am pretty confident about being able to do it my self or with my stepdad's help but another question. The wiring that was installed with the U-Haul hitch(not installed at U-Haul) that gave me the plug I have now stays and the module goes before the plug in line with the wiring, correct? I have a few local U-hauls and a couple camper rv shops too so I will try them. Thanks again

The "Drawtite" ones we have, have a new flat four on the end, so you'll be replacing everything. You might be able to find an "in line" replacement, but it would be better to find one that replaces everthing (the converter and wiring harness are all molded - less chance of a bad connection or water corrosion)

Thanks,really appreciate your help and now the search for it begins.

Try Northern Hydraulic on Pembroke Blvd, they have a plug & play light kit for Tacoma's that has the modulator wired in. Takes about 15 minutes to install.

Towing and Rv trailer with 7 pin connector

Bill, I have had my Tacoma wired for a 4 pin connector at the dealership. Now I need to go to a 7 pin for my RV trailer. Currently I have a 4 pin at the Taco, to 7 pin at the trailer adaptor but would like to go to the 7 pin to 7 pin in order to run fridge while under tow ( Idon't have a trailer battery yet but intend to get one and a solar panel for it). With the current wiring the left blinker on the rv doesn't work, will change the bulbs later today, may solve the problem. Anything I should know? The tail lights of the trailer are riveted onto the trailer. It is a 1980 Trillium 4500 fiberglass 15 footer.
