Re: gauge wiring
This truck is really starting to get on my nerves. I am going to go out and check in a minute but I dont understand something. I have four wires coming out of the firewall for gauges: Tan, Blue, Green, Brown. I see on the diagram where it says tan used for gauges only on the oilsender but I see a Drk Blue for oil pressure switch also
Green I know is for Temp, It pegs when I hook it up Probably bad sender
Brown goes to the Alternater but I still cant get the Volt gauge to work
Tan I have hooked to the Fuel Gauge and it seems to work, it was hooked up there before and when I put gas in, It went up Besides there was one of the diagrams that showed the tan going to the fuel sender
The Dark Blue, I have it hooked to the oil sender, It seems ok, It reads a little low but goes up to almost 30 when I rev as do most GM have low pressure at idle. The blue shows to oil pressure on the same diagram you refer to but with about three other wires and then above that, it shows a tan wire going to the oil sender and say on gauge only clusters.
I m trying to follow what you had said about the pins, are you talking about the ones that go to the cluster
then there is the ground thing, Any pictures
