Euro turn signal side marker conversion


Recommended Posts

If you want your side markers to act as turn signals this is what you do:

- Remove CD changer if fitted 
- remove front carpet pieces left and right
- remove plastic cover around brake fluid tank to access wiring loom
- remove slotted plastic cover under CD changer 
- pull back carpet on pass side to access wiring loom
- unwrap wiring loom and look for gray-red 0.75 wire
- follow wire until it splits into gy-rd 0.75 (parking light) and gy-rd 0.5 (side marker) (approx underneath xenon headlight leveling box)
- cut thin gy-rd 0.5 wire, isolate end going to firewall
- Find 0.75 black-green wire (turn signal) near end of cut gy-rd 0.5 wire, strip isolation and connect both wires. Solder and isolate.
- Passenger side is now done
- on driver side locate big white plug and find 2 gray-black wires coming out of the plug. One is 0.5 (side marker) and one is 0.75 (parking light)
- cut thinner gy-bk 0.5 wire directly at the plug 
- find 0.75 black-white wire (turn signal) and strip isolation 
- connect gy-bk 0.5 to bk-wh 0.75 wire, solder and isolate
- reassemble
- Enjoy Euro turn signals

I first did not find the thin gray-red wire on the pass side and made the mistake of cutting the 0.75 gy-rd upstream of the split. I had to patch a wire in to fix the parking light but everything works great.

Bonus effect: Now you see if your alarm is armed when you walk away sideways.
