wire harness question
ok guys, and especially subford ( as i know he has a butt-load of illustrations ) my temp and oil pressure gauges dont work on the dash of my 89 f250, i tried 2 different clusters that i know work, and still same dead gauges, i believe it is in the wiring coming from the firewall harness up to the harness that goes to the cluster, my big thing is this, does anyone have a diagram of what is where in the big round harness that comes in through the firewall.... thanks in advance

I think but not 100% sure that pin #38 is the oil pressure gauge and should be a white wire with a red stripe.
I also think but not 100% sure that pin #17 is the water temp gauge and should be a red wire with a white stripe.
