In order to keep better track of maintenance intervals I would like to install a third-party hourmeter on my boat w/ 1999 Yamaha SX200TXRX.<br /><br />Here is a shot of the wiring behind the standard Yamaha multi-gauges:<br /><br />
<br /><br />From what I understand, the yellow wire has +12V when the ignition key is ON, correct? <br /><br />What is the best way to tap into this wire? Just a simple cut and splice with heat-shrink butt connectors? Or should I try to see if there is a way to connect in with the wiring harness directly?<br /><br />Thanks,<br /><br />-- Tom
