Anyone know the pin out for the fuel pump relay for a 1996 4.3 Gl Volvo Penta
with a Holly 2 Bbl carb

There are 5 wires to the relay

Red= 12 all the time
Yellow with Red Stripe=fuel pump + side
Black= Fuel Pump - side
Orange= Don't know
Green = Don't know

Any idea whats controlling the orange and green wire

The orange wire comes from the start relay, and the green wire comes from the alternator. Both go thru diodes.

Thanks for the print out I think this is my problem.
Got a new relay this morning and everything seems ok running on the muffs

opened up old relay and found some corrosion all in it.

Headed to to lake now to give it a try
