When my 1990 Rinker 206 Captiva got a motor swap (5.7L Merc. for a new chevy 350) and new ignition, a few things were never hooked up or they no longer work, the swap was done before I bought the boat. The tach works, but the speedo, engine temp, and tilt guages do not. The Merc. electronics module was removed when the new ignition was installed. Anyone have a wiring diagram of where the wires hook up, or would hook up to the motor, or are able to walk me through it? thanks.
