Adding turn signals to 2015+ HD tow mirrors

[block8head]

I purchased two 5 pin 12v 30/40a relays from the auto parts store and successfully hooked them up to give me turn and running lights to the amber LED.

Simple connections:

Pin 85 - Ground

Pin 86 - turn signal (from truck)

Pin 87 - DO NOT USE

Pin 87a - To Amber LED on mirror

Pin 30 - Running light (from truck)

 

Once connected you are good to go!

I'm gonna give it a try this weekend. Thanks for sharing. ;)

Mostly. What you're describing gives you running lights and turn signals, yes, but only when the running (parking) lamps are powered. When you don't have the parking lamps on, you won't have turn signals on either. The turn signals on the mirrors are also inverted from the rest of the turn signals on the truck.

 

If you want them working even when your parking lamps are off, you would need to wire them like the XOR relay setup I posted in the first post in this thread.

True however all he needs to do is hook a diode from 86 to 87a , a diode coming into 30, and it will work. this is the kit I plan on making for mine. Of course they won't dim and come on at full bright, but it will achieve the same end result.

I did mine as parking lights and blinkers

I did mine as turn signals for both amber and the directional arrows and the LED spots are connected to the back-up lights. After all, they are intended to help you see down the length of your trailer.

Any pics please ?

Have fun with that. It's not going to work how you think it's going to work.

try this

I'm in for the Dummy proof version!

How so? The diode's are taking place of your other relay. The amber will "flash" opposite of the rest of the signals, but will still act as a flasher. Unless there's something completely different about how these trucks are wired.

You are defeating the point of the relay. Upon turn signal input, the relay is cutting power to 87a by energizing the coil. If you have a diode going from 86 to 87a, then when the parking lamp input is on, the light won't blink because you're getting current from that instead. If you can manage to source enough current through the relay's coil in the first place - they aren't meant to do that.

 

jakewake23: I like the setup. How are you dimming the parking lamp input?

I've got a resistor and a diode wired into to the power wire running into the and then i just ran a wire from the blinkers with a diode wired into that power wire above that resistor.

Phydiux any new updates as to when you will have all the components for the PNP version?

^{Any updates on this or is project dead?}

[Gmcant33]

....any updates or has anyone figured out an alternate route ??
