Cummins oil pressure senders

Still struggling with fine tuning my Actisense to garmin glass dash conversion on my 2000 4160 with mechanical 6BTA Cummins power. Oil senders are single wire vs Cummins oem from Sbmar show two wire. Anybody know part numbers or ohm vs pressure curve info for these senders which Regal must have specified combined with the needlessly complicated Medallion gauge setup? 

Thanks in advance for any input
