From: Jerry Avins on
I need to install a trailer light power converter, and it would be a
great help if I knew where I could get access to most of the wires in
one place. (I'll have to run a hot wire to the battery, but I can hack
that.) Is there a place I can get a wiring diagram without buying a
service manual from the dealer? Are there third-party manuals available?

TIA

Did mine a couple months ago. All of the wires were easily accessible from
the two small hatches in the corners. I found the installation instructions
on a T-Connector website very helpful.

Here is the color code info:
Factory harness colours are:

passenger side
green/yellow stripe : green (right blinker)

drivers side
green/yellow stripe : yellow (left blinker)
solid green : brown (headlights)
green/white stripe : red (brakes)
white/black stripe : brown (ground)

If you use the ground wire, when you use your blinkers with a trailer hooked
up, your dash lights will blink 2 or 3 times until the relay catches up.

For $10/day, you can get online access to the factory service manuals,
wiring diagrams, etc. at techinfo.toyota.com.

Thanks. I might do that, but DB's information is probably enough. I was
hoping to find a break-out location that had all the cinnections in the
same place so I don't need to run wires across the cargo area. Maybe
I'll run them under the floor by drilling through.

What I call tail lights, no?

Also brown? In my trailer harness, it's white.

The trailer was a kit that came in 3 50-lb boxes. It's powder painted
and bolted together. There's no indication in the assembly instructions
that any scraping needs to be done, and the instructions say to use the
frame as ground. I've been there too many times. I ran a ground wire all
around. As far as I'm concerned, the hitch ball can ground the frame. Or
not.

Thanks. The color codes will make installation much easier.

There's a "power converter" that goes between the car's wires and the
trailer's. It takes power from the battery and uses the car's wires as
low-power signals to drive the outputs. I could have built one, but I'm
getting lazy in my old age. I'm thinking of adding a back-up light, but
that can come later.
