Re: Adding a trim gauge to my Evinrude
You don't need any special harness to wire in a trim guage . As long as your motor has a sending unit on the swivel bracket ( the bracket that connects your motor to the transom ). Wiring in a guage is really very simple . There will be two wires coming from the sending unit , one will go to the ground on the guage , and the other will go to the "S" terminal on the guage . The guage itself will have one hot wire coming from your ignition switch ( or any other hot source for that matter ) , that connects to your "I" terminal on the guage , and then a ground wire . That is pretty much it . The key is whether or not your motor has the sending unit or not .
