I am installing a cowl mounted trim switch on a 1998 Force 40 HP Outboard. The Green and Blue wire hookup is a no-brainer since they just plug inline with the existing wiring to the relays. My question is the Red wire ?? Does this just go to any hot lead from the battery, or is this something that needs to be tapped into one of the relays, or hooked to some other harness I'm unaware of ?? I'd appreciate any help and direction I could get on this, I'd rather not fry a $75 switch. Thank You.
