Here is how i have wired my option switch on my V4...
But the LED is lit all the time... what am i missing :S
hope someone can see what iv done lol!
cheers

Second time I have wrote this as I delited it
The reason is the switch should have a positive feed and it earths in the ECU. So what you have done is caused the ECU to get the positve feed through the LED supply
What you need to do is change the earth from the switch to a positive feed and then put the LED in line on the wire from the switch to the ECU.

Woah there geeky dude! Don't put +12V on that pin of the ECU - it grounds the option output to enable the map switching. With the shift light and option outputs you'd feed it 12V so it earths through the ECU.mini-geek wrote:Second time I have wrote this as I delited it

I'd try a diode in-line between the ECU and where your LED taps into the switch wire (with the marker bar pointing away from the ECU), to isolate the LED from the ECU.
i wired it by the instrucions on here, the switch doesn't need 12v, it just goes to ground...
The MJ is give about 5v through so the led is seeing both ends...
I cant change this switch for anything else...
Hmm, thinking about it, if i use i diode between the led and the option switch line... that should work... right?
Maybe some sleep will get me back on track!
cheers
