Somebody help me out with this schematic:
I am tracking that a new wire must be run from the battery to the terminal marked "87".
I think a wire is supposed to be run from the terminal marked "30" to the back of the PP display where there is currently a purple wire. This wire will replace the purple wire. What happens to the other end of the purple wire?
Now for the black and purple wire that goes to the PP logic module. Does the black wire get disconnected from the tach and then a new wire runs from terminal "86" to the ground on the tach? And what is the deal with that purple wire?
I am so confused.
