Finally ran my depth gauge transducer and installed the guage in the dash Have to connect the + and- wires. Landed the neg wire to the grounding buss but haven't been able to locate a suitable tap for the + that is swithed with the ignition. Anyone have any ideas on wire color or location to trace down? This would be so easy with a schematic!

Any help or a pic or 2 would be appreciated!

You can tap it off the hour meter...

Most of the guages should have a common + that is switched from the ignition. I believe it is a purple wire on most of the guages but check it with a meter or a test light first.

I connected mine direct to th switch itself.. There were several wires connect there already.

Thanks. Will try locating a purple wire first and if no go will give the ignition switch a try

Thanks to each of you for your help!

Took folks advice and looked for purple wire and used continuity light. Found the two purple wire running to the kill switch and tapped in. Works perfect and now is only running when key is on. Thanks to all for your help
