I am trying to install a third brake light replacement, and the light has 2 wires (red and black) coming out of it. How do I attach these to the oem plugin harness? Do I just cut the sheaths back a half inch and stuff them into the 2 plugin holes (red into black/yellow, and black into black) and electrical tape it secure? Or should i go on the hunt for some sort of connector? I own a soldering iron...but really dont know how to use it well.

Thanks in advance! Sorry for being a wiring noob, but ive searched for quite a while for a good answer and cant find one.

You can find some 7440 pigtail connectors so you don't have to cut any OEM wires.

Here are some installation pictures for my unit. I also installed a flasher unit that only flashes when I brake very hard.



(The red wire popped loose from the butt connector connecting to the yellow wire. It was fixed.)

Also, if you have an S1, an LED 3rd brake light may trigger the ABS light on your dash. You will have to connect a load resistor in parallel.

Awesome work, i did come across your original post while searching, but didnt realise it was simpler than it looked.

I'll look into the pigtail connector...i was even thinking of just cutting the plugin off and just wire nutting the wires together, so if that pigtail allows me to not destroy the plugin, i like that. Thank you!

It only looks difficult because of the flasher, which has quite a few wires coming out of it. It also has a very good instruction manual, though, so it was not difficult to add to the circuit.

Without the flasher, the red and black wires coming out of the LED lamp just connect to the wires coming out of the pigtail. You then tap the wires out of the pigtail and add a load resistor so you don't have the ABS malfunction.

I've been searching and can only find this female pigtail 7440...it doesnt seem right, and doesnt look like the one you used...

maybe I'll just cut the wire and directly splice into it instead...

This looks more lule what you used...do I need a male pigtail?

Yes, this one will work.

I just like to keep the OEM socket in case I want to go back.

You're absolutely right, better to keep the oem socket. I have ordered that one, and will install with it...strip a bit off of each end of wires and solder them together with some flux.

Thanks for all the help!
