Fuel Management Gauge wiring instructions.

[hookemup29]

Hello, Iam trying to install a Yamaha Fuel Management gauge. Do you guys have an owners manual for usage and install instructions on how to properly rig it? The FM gauge has 5 wires with male plugs..
I dont have any loose plugs hanging from my wiring harness so I assume I will need to splice into the existing wires. Where do you recommend the best place to splice in is. Between the key ignition and wiring plug or after the plug before it goes back into the boat?

Thanks

The Yamaha gauge harness should have multi connection bullet connector on gauge end of harness, if all connections are used then you can order multi connect wire leads and will allow for three connections per lead.
