YTMercedes  Actros MP2 2008 LED Upgrade/Install info
Hi all,

Has anyone setup a DIY or a guide with schematics for rear factory tail light retrofit to LEDs?

Wiring plug color/function?
Resistors, how many needed, where to wire...
Is it one resistor each for each brake light, each indicator? Or does indicator need relay?

So confusing, but simple! I wish i had an auto electrician friend think

It's not an issue of figuring out what wires do what function on new LEDs asthey all have schematics. Easy!

Just factory wiring is the question


I can't find info anywhere! fail

Any help would be appreciated.
I might have time to make a detailed how-to and post if i'm successful..

Thoughts? dontknow

You only need to turn the lamp on. and in the DAS turn off the control of the bulbs,

Ok so, managed to get it to work...
Basically used 3, 24v load resitors at either end of the tail lights.
1. Indicators
2. Reverse lights
3. Stop light...

Now its important to note that my leds were hyperflashing when i connected resistor to 1. Indicators. 2. Reverse lights and 3 parkers/tail lights. My stop lights were working perfect without the resistor and i didn't think i would need a resistor on stop circuit, but for some reason if there was no resistor on stop circuit. The whole tail light assembly would hyperflash when i turn on parkers.....

So save yourself 5 hours of headscratching and remember that for whatever reason, connect

1. Indicators
2. Reverse lights
3. Stop light...

Connect a resistor to those 3 only (3 on each side)

If you have 2 separate stop/tail light curcuits per side, just join them together to share 1 resistor....

Overall pretty straight forward..

Hope that helps someone!!!
