Re: Installing a tach on a 79 90hp Mercury
I found a brown wire back at the engine that wasn't connected to anything. So I hooked it up to one of the yellow wires coming from the stator. And it is the same brown wire up at the plug. Both the black and white wires checked out ok too, so I should be good to go. Thanks for your help. Does anyone have any suggestions for a nice, quick, easy, good way to avoid paying $50 for a harness that plugs into my tach plug at the control box?
Thanks
