So which one works for a 2004?
lol
Key question about the 7 pin plug and your trailer.
Does your trailer have one bulb per side that is used for both signaling and brakes? Or do you have separate bulbs?
It looks like the job of the flasher is to send signal blinks to the trailer, unless the brake pedal is pushed. Then it over-rides the signaling function and does something other than blinking...but just for the trailer lights.
I'm going to assume you have a shared bulb setup on the trailer. Tell me this, with your trailer connected...
Run the truck, signal left or right. Observe trailer lights, then have someone press brakes (while signaling). What happens to the light bulb that was blinking on the trailer in the direction being signaled? Does it continue to blink and the other side of the trailer comes on solid?
Stop signaling, now turn on hazards, observe trailer lights. Then have someone press brake pedal (while hazards on), what happens to the lights that were blinking on the trailer?
Do they both continue to blink, or do they both come on solid?
... if I were to add more logic to TapTurn to handle trailer lights, I need to know what it should do!
Thanks
Sorry for not posting last night - beer and internets mix poorly.
Here is a youtube video I uploaded this morning -

The video is public but unlisted, you can only get to it from this link.
It shows all possible light behavior.
Running lights on/off
Brake lights on/off
Turn and 4 way on/off
Brake on + turn signal on
running lights + brake + turn
You can tell when the running lights are on because the rear side markers illuminate as well as the tail lights.
Don't judge me on the cleanliness of the trailer! I have not had time to give it the first cleaning of the year as I live in the land of the 6 month long winter.
Any updates on this project?
Bump back to the top for an update.
Before I go under my dash, this new product by diode dynamics wont fit into that plug right? it says it should fit up to 2009 4runners so i have my doubts. Maybe it could work with modifications?I just installed what I would call a beta model I received from Scott.![]()
First thing I have a 2013 SR5. The turn signal module is not like that in other cars. Instead of it plugging in like a relay. It is a harness.![]()
I had direction from tap turn as to which wires went where. It was a bit difficult as the schematic I pulled from Toyota didn't match what it said it was as far as color and position. Also, there were multiple green and multiple red lines that made it a bit trial and error.
Also there isn't a direct plug in so I spliced in after the harness.![]()
I know it looks a mess but I did a nice job zipping it all up.
So a couple of things. It deactivates the drl. I have never used them so I don't mind. If I want drl I will just use the headlights.
The other thing that I have not confirmed is that it makes the trailer electrical not work. Scott told me that I can use a 5 pin adapter to get it to work, but I haven't tried. Maybe later this week.
Other than that it is full functional.
