Just playing around with my dash setup, and noticed that the horn works all the time, regardless of the position of the ignition key.
Following things throughIi have sort of worked out that :-
a) PURPLE is live 12+ all the time, seen on the Aux Plug and the Horn - PURPLE all the way back to the fuse block
b) GREEN is switched 12+, from the Ignition key
c) BLACK is common GROUND
Just checking I've got things straight?
I'm surprised the horn is operational all the time, was expecting it to be switched.
On the same subject I'm assuming on my Sport250 start button, this would only be illuminated with the lights, as its quite a bright RED?
