96-2000 Fuel gauge

Good deal, It would be nice to have only 1 pcm though. Can you read the output from the pcm in ohms and voltage? I know there's a 5 volt sensor return but I want to see what C1 pin 9 fuel level input and C3 pin 13 fuel level output are. Just ground one side of the voltmeter and prick the wire going to pin 9 and 13 to see what they show and please post it. Make sure the ignition is on......................LOL

Thanks

Blue connector = C1
Red connector = C2
Clear connector = C3
Black connector = C4

If you unplug the connectors you can read the pin numbers on them. You'll need to turn the ignition on and read the C3 female pin 13 connector itself first (not the pcm) then plug it back in and read C1 male pin 9 on the pcm (not the connector).
