I need some help with the wiring of my new combo gauge from Palo Alto:

The old gauge had a red light for generator, red light for low fuel, oil temp light and oil pressure light green and brake warning light red. The new combo gauge has green, red and blue. What from the old gauge is supposed to go into what on the new gauge?

The combo gauges each have 3 connections. ground (ground symbol), positive 12 volts (+ symbol) and the gauge sensor (G), right? Comparing old to new: for example, in the factory manual (914-6) and for my old gauge, the oil temperature sensor, #11, went to the gauge. There was a connection #10 called "terminal #15" that went to both the oil gauge and the fuel gauge (I think). Is that the 12 volts for the gauge? Ground was provided through the casing?

For the old oil pressure light, there is a green/red wire on the outside connection and 2 red/white on the inside connection. the red/white wire seems to go to all the bulb connections. Is the green/red the old sensor and the red/white 12 volt power, or what?

I didn't label wire #12, fuel sensor well. Is it a green wire do you know?

Finally, according to the manual, going across the back of the old gauge from right to left on the horizontal diameter, there was:

#9, oil pressure light
#8, brake warning light
#0, not used
#5, generator light

but, in fact, according to my notes, #0 was used. there is a black wire on the outside and the red/white on the inside connector. Do you know what this was/is?

got the old pressure sender off with a crows foot, 17mm I think. wire all the "+" gauge connections together and then attached that to one of the car red/white wires. Did the same thing for the ground connections. This was easier than trying to connect the shorter wires in the car. Then we just hooked each wire from the sender for the gas tank, the oil temp and the oil pressure. Checked continuity just to be sure. I used the former oil pressure idiot light wire as the wire for the pressure gauge. I have not yet run a new wire so that there is both a gauge and a light for oil pressure. All the gauges seem to be working. I have lights for the generator and the low fuel level. Palo Alto did a great job on the gauges. They look great. They aren't much help getting them wired in -- figuring that the car owner can figure it out. But you guys helped me there. THANKS! Finally had a nice weekend to drive, too. I am psyched!!
