Engine install questions

[Wildman_fab]

I just installed a 1994 ocean pro 225 on the back of my Mako. We got it all pluged in, primed and she fired right up! After that we tried to hookup the tach, and no dice. The needle droped down to zero after starting, but never registered anything else.

Last weekend we ran it and it went great, but without a tach I don't know if I am getting WOT and I cant check my prop size.

Its a new factory mako gauge that I bought as a package. I have tried to switch the setting on the back of the guage with no results. I believe we have it hooked up right, but I cant find the correct diagram on the PDF manual I have to double check it.

I was looking at the wire harness last night and I see another pair of ring terminals, also poking out of the main engine harness, what are these for?
Any info would be great, this weekend we are going to hook up a buddy's 'extra' tach to see if that registers.

how can anyone help if you don't give a clue as to what color the wires are.

I was going to wright a smart *** comment back, but instead Ill say this:
1. The tach works now that I swaped the wires around after testing with a meeter, my buddy hooked them up backwards.

2. The wires are black and white, with the same small size ring terminals as above. I do not get any current a crossed them when the key is in the ON position.

Re: Engine install questions

Tach wires should be purple, black and grey.

Re: Engine install questions

If the black & white wires are in together then those should be for the trim gauge.

Yep I peeled the harnes back andfoudn that it was accualy attached to the trim and tilt harness, not the main like I had thought, PO had taped them up.

Re: Engine install questions

trim/tilt wiring is black with brown stripe and white with a brown stripe.
At least for the guage.
I have a 94 too, I know the colors because I just stole them for my temp guage wiring.
