Just picked up an older 115 Evinrude and the power pilot control box. he guy gave me a CMC power tilt trim unit for it as the 115 didnt have one. Question is how do I wire it up? It has two wires coming from it. The control box doesnt have a tilt/trim switch on the handle. Thanks for any help. First time messing with a boat motor. Its going on a 24' Pontoon
