Hooking up fuel flow meter

[dbric36]

I have everything installed but don't know where to tie in the + and - behind the dash of my 1993 270 Sea Ray so that it comes on when the ignition is turned on. To many wires behind the dash and I have no idea where to tie in.

Re: Hooking up fuel flow meter

Any of the gauges (except for the speedometer) have a + and - connection on them so they become active when the key is in the RUN position. Check the wire colors on the tachometer. The terminals are usually well labeled. You can tie into the same color wires on any of the gauges. Make sure your fuel flow turbine is facing upward or as close to vertical as possible.
