The purple wire is for the light. You can branch off from that to pos. Make sure it's grounded.

if you have a separate light switch it won't be accurate. Then you have to feed it with a direct positive line that comes on with the inigtion.

Go for the ign switch at the helm Isolate the termial by turn switch to the on position and use a Volt meter to find it. Don't start the engine. You will have one terminal that stays hot all the time dont't use that one.
