wiring diagram for my boat tachometer

[harry513@msn.com]

I AM TRYING TO HOOK UP MY WIRES BACKUP TO MY TACH WHICH IS IN MY BOAT. THERE ARE FIVE WIRES TOTAL THAT ARE COMING FROM THE HARNESS FROM MY THROTTLE CONTROL. THE COLOR OF THE WIRES ARE AS FOLLOWS:<br />(PURPLE) (GRAY) (BROWN W/WHITE STRIPE) (BLACK) (LIGHT BROWN)<br /><br />NOW ON THE TACHOMETER THERE ARE 4 TERMINALS, 2 OF WHICH I CAN IDENTIFY; ONE IS "IGN" AND THE OTHER IS "SEND". THE OTHER TWO TERMINALS I CAN'T IDENTIFY. ALSO ON THE TACHOMETER, THERE IS A BLUE WIRE THAT IS ALREADY CONNECTED TO THE "IGN" TERMINAL AND TO ONE OF THE TERMINALS THAT I CANNOT IDENTIFY. LOOKING AT THE BACK OF THE TACHOMETER, THE "IGN" AND "SEND" TERMINALS ARE SIDE BY SIDE; ALSO THERE IS A TERMINAL(WHICH I CAN'T IDENTIFY) IS LOCATED ABOVE THE "IGN/SEND" TERMINALS. THE OTHER TERMINAL I COULDN'T IDENTIFY IS LOCATED FURTHER UP AND IS BY THE SOCKET/BULB FOR ILLUMINATION. THIS TERMINAL IS ALSO THE ONE THAT THE BLUE WIRE IS CONNECTED TO FROM THE "IGN" TERMINAL. <br /><br />THE MOTOR/THROTTLE CONTROL IS A 1999 MERCURY 50hp. IF YOU NEED MORE INFO, PLEASE E-MAIL ME BACK OF WHAT YOU WOULD NEED. I APPRECIATE IF YOU CAN ASSIST ME.<br /><br />THANK YOU----EDDIE OLIVIER

Hi Harry,<br /><br />Click the link below to the Teleflex site and then select the type of engine you have and take a look at the installation guide. Tachs and wire color codes are pretty much standard so the site should do it for you:<br /><br /> Teleflex Support page
