Oil inj module wiring

[mt1973]

I'm putting a 89 175hp on my ski boat for social use.
Can anyone tell where the green wire from the oil inj warning module goes ?
The manual I have says, it goes to the switch box but does tell me which spot on the box.
Cheers

have you thought about removing the oil injection? it's great peace of mind to know if the motor's getting fuel, its getting oil

This is the first time i'm putting it on one of my boats. I have it for sale and the guy that is interested wants it on. It is a worry but there are alot of motors still using it.
I may still take it off yet.

All connected up and bleed.

I removed the line to check oil pump flow, oil is slowly dripping from the pump and the drips increase as the revs are increased (if that makes sense)
Is this normal I expected more of a constant flow to open the valve on the tee to the fuel line ?

At idle is is around 100:1 which is only 1% oil. At WOT it is 50:1 which is only 2% oil. The check valve is a 2 psi valve. You can use a pressure gauge to see what the oil pump is able to produce. I can send you a manual that has all the stuff in it for the oil injection you need to know if you want.

A copy of the manual would be great thanks.

Sent ya a pm with the link for the manual. Good luck! It is the same system as the 2.4 just minor differences like fuel pump mounted check vale instead of in-line.
