Oho! Apparently these gauges are a little more involved than the 2-wire kind I'm used to: http://auto.howstuffworks.com/fuel-gauge1.htm I pulled a Chevy wiring diagram, and sure enough, the gauge has a connection to +V (tan), a connection to ground (direct), and a connection to the sender (brown). I'm unclear on how it works internally, so trying to fake it up with a parallel resistor like with a 2-wire gauge may well not work as expected. Sorry about that. Anybody know what's in the 3-wire gauges? - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
