Need an answer about the air system on a M923.

TM-9-2320-272-24-4 FO 5 shows the airline going from the secondary air reservoir to the secondary ABS relay valve and the airline from the primary airline going to the primary ABS relay valve. The P2P Setup shows lines going from the primary reservoir to both of the ABS relay valves. I'm thinking the TM is wrong. Your thoughts.

Did you check over in the TM section under the ABS MWO? http://www.steelsoldiers.com/showthread.php?79228-TM-s-for-the-939-series-trucks
You may have an older version of the TM.
