2 questions: First, Someone gave me a "Polaris" tachometer (it has yellow, black, and ground wire on nut) My ignition wiring cable has red, green, black, brown, blue, yellow. I know that blue is choke, brown goes to starter solenoid. Is yellow the accessory? How do I hook up the tach? Second, Is there a power trim/tilt available for this unit? Where would I find one, since when I ask local boat shop, the response is "they don't make anything for this model anymore."
