Gen 3 Towing Thread

I use Milenco Grand Aero Mirrors; They attach solid and don't shake.

Thanks for the input. I will check out both of those options and decide which might be best.

 

I was hoping for some help here. I have a 2017 Dbl Cab sport 4x4. I had the dealership install the tow package. It has a 4 pin adabtor in the back.

I’ve recently got a great deal on a used camper trailer. Problem is it’s a 7 pin and has trailer breaks. It’s a light weight camper (2400lbs) and tows fine without the break assist but I kinda want to have them.

Is there an easy way to convert a 4 pin to a 7 without re wiring the whole thing?

Should I just run a new 7 pin line with a trailer brake controller?

If I just use a 4-7 converter I would only get lights and no brakes correct?

Right now I just need to get it moved so trying to at least get the lights working.

Any help would be appreciated. Thank you.

 

I thought all 3rd gen factory/OEM tow packages included both 4 and 7 pin? (Someone correct me if I'm wrong, I only really started looking at buying a Taco in 2018 so don't know as much about options before then.) But if that is true they might have just sold you an aftermarket hitch and wiring and not a true Toyota tow package. If so, then that means you also likely don't have the tranny fluid cooler either, which I think is pretty important for towing anything significant like a camper especially over long distances/extended durations.

As far as trailer brakes are concerned, you might to check local laws as I think some states require them only over certain weights, but others basically say that if your trailer has them you HAVE to use them. Of course how much this is enforced I'm not sure, but could affect insurance claims etc if you ever have to submit.

As far as getting going for now, yes I think a 4>7 converter would probably get you at least lights, but obviously not trailer brakes since that is what the extra wires are for!

 

I should have specified. It did not come with the OEM tow package. They installed the wiring and hitch.

 

A 4-7 adapter should get you lights to get it moved. If you want to use the brakes, you'll have to run some more wires and might as well just start with a nice 7 way harness.
Something like this will be a simple as you can probably go to get brake function: https://www.etrailer.com/Custom-Fit-Vehicle-Wiring/Toyota/Tacoma/2017/22117.html?vehicleid=201761705

 

I recently pulled an '04 Wrangler on a steel car trailer for about 20 miles. Was pleasantly surprised at how well the '18 Tacoma handled it. Felt like it did a bit better than my old '15 did pulling less weight. Seemed to have plenty of power but I was pretty sure I trashed the rear leafs. They seem to have recovered though.

That being said, the '15 was a better daily driver.

 

I pull a 20 foot Bay Boat with my 2016 TRD OR. At first it seemed to struggle searching for the right gear to be in. Now I put the transmission into Sport Mode 5th gear, and leave it there. Pulls like a dream, no sway, no searching. MPG pulling the boat is usually between 14-16, not too shabby IMO.

 

Might be a dumb question but if my truck came from the factory with a tow hitch is it safe to say I have the tow package?

 

Yes?

 

A 4 to 7 pin adapter costs less than 20 dollars. The trailer brakes won't work but the lights will. I would think even a regular auto parts store would have them.

 

We pull a little Jayco RB145. It pulls well, and I’ve got Dakars out back to overcome any excess squat.

 

Not a dumb question. Wouldn't be unheard of for a port or dealer to just add the hitch and wiring without the other goodies. Do you have a 7 and 4 pin plug in your rear bumper near the license plate? Do you have an additional cooler (looks like a mini radiator) behind you main radiator?

 

Thanks, I’ll have to take a look today.

 

We have the same trailer, just the Baja version. My 3rd Gen 4Runner wasn't happy towing it on 33s, but did it anyways. Good to confirm it should be a breeze with the Tacoma.
Great little trailers.
Thanks

 

Thanks again, Just checked I have both sets of pins in bumper and a trans cooler on front of the radiator. Just installed a brake controller.

 

That’s about the size of the camper I have. Jayco kiwi. Definitely squats a little with it attached. Thanks for the advice. Might have to invest in some Dakar’s.

Looks like im gonna grab the 4-7 converter to get her moved and add a new wiring harness And trailer brake.

Do you have the tow package? Should I be concerned about not having it as far a fluid temps and alternator amperage? I’m not entirely sure yet if the factory alternator will charge the campers battery. Gotta do a little more research.

 

Exactly what I was looking at. Thanks.

 

All very good questions! My truck does have a factory receiver and 7-pin connector, but I’m unsure of any mechanical upgrades. You should be fine either way I would think, unless towing in the mountains... Pretty sure the truck will not charge the trailers battery. Anyone?

 

^^^Pretty sure my camper charges the battery while towing. I run the fridge off the battery and it is always fully charged when I get to the site. I do have a built in inverter. 7 pin with tow package. Will have to test this theory when I hook it up next, will run down the battery a bit check voltage pre and post.
