Can anyone help me with wiring info for the fuel gauge in a 1988 suburban? The sender I am finding has an orange wire at the tank, but I need to identify the wire going to the gauge. I thought it would be the same orange wire, but I dont' see it under the dash. I am wiring in the sender for an auxillary tank and want to be able to switch between the two senders going to the factory gauge. Thanks in advance.
