Swapping cluster from idiot lights to gauges

[5150]

I know there are several threads on this, but still not getting it. I hated to revive a 3 year old thread so I'll start my own.

I have an 87 R10 that has idiot lights. I'm swapping it to a gauge cluster that I picked up from the junkyard. Here is a pic of the before harness?






I followed one of the older threads directions but I ran into a few problems.

1. My fuel gauge doesn't work(pegged at 3:00 and it has a new sending unit)
2. Oil Pressure Gauge doesn't work (pegged at 3:00 also)
3. Temp Gauge does not work(just won't move at all)

I grabbed a harness off of an 80's model with gauges at the junkyard, but decided to repin most of it. I have two/three wires left over. It appears one is the Brown 25 and the other is the Brown 50. Also there is a brown wire with a white stripe that I can't find on any wiring diagram. Here's a pic of the current harness:







After reading all of this I hope you're not as confused as I am.
