E38 PCM Flex Fuel Senor Install
Thanks for all the help on other posts. I think this is more detailed than anything I could find. I'll post up the parameters in the tune I changed to activate the sensor .

Good job on adding the wire loom, since the back of the motor does get hot.
But not a fan of red wire used for the ground wire.
Hence use red wire for positive wire to your 12 volt source, black wire for ground wire to frame, and just pick an other color like white for the wire to the ECM pin.
Regarding the added ECM pin, if you notice on the rest of the harness connector wires, they have rubber rings backers, to prevent water from getting through the wires to the connectors. So worse case if you can not find the needed o type wire backer grommet, then at least use some RTV to seal off the wire to connector back of block isntead.
