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
