2000 Johnson Wiring...???

So I have a 2000 Johnson 150 which used to run on old controls (when the repowered the '84 controls stayed and they used an adapter to hook up the post '96 johnson). I just installed new controls and cables and everything works (except tach, see below) but I can't figure out how to power the gauges (fuel and volt). On the old controls there was a two wire plug that went hot when the ignition came on and that juiced the two gauges. Now with the new controls there is only a 8 pin plug to the system check/tach but without splicing into one of those wires there is no hot for the other gauges. Any suggestions? I am thinking there may be a hot off the tach that I jumper to the others but can't figure it out.

Onto the tach, I need an extension for the 8 pin plug from the controls to the dash, is this the right part???

Part #176717

It sounds right, but that is the ONLY place that has it, weird...

Any help would be greatly appreciated. Thanks.

S- Just finished installing a 2000 Evinrude FICHT 150 on my boat. Spent considerable time re-wiring the dash area (new gauges and GPS). Anyhow, this much I do remember for certain - the hot wire is colored purple. I cant say for sure where it comes from - but I want to say it is in the same harness bundle as the 8 pin connector to the Tach. I can take off my dash tomorrow - and check it out for you. The p/n for the cable extension looks to be the right one - from what I can tell.

By the way - what do you get for performance from that engine ? I took mine for the 1st test run this afternoon - WOT gave me 38 mph @ 5200 rpm. MPH by GPS. Prop is OEM 15x17. I was hoping for a little better !

Thanks for the help. I figured it out (with a little help from the THT board) and you are correct. Purple is keyed hot but on the Tach/system check I didn't want to splice it so I used on of the bare purple wires from the other tach setup. The harness has an 8 pin plug for tach/system check and then two sets of three bare wires, one for tach and one for system check so if you didn't have a combo gauge you can use those. I grabbed one of the purple wires from them and used that, capped the others and are good to go.

For performance (now that I have a tach) I am getting average 41.5 WOT at 5400, that is trimmed and full fuel two POB. Trimmed in she maxes at 38/39 at 5100. I am swinging a 15x17 OEM SS prop. Your WOT sounds about right if you haven't trimmed her out. Now that I have a tach I will be doing some more research on what works.
