Norway Posted March 20, 2014 Share Posted March 20, 2014 (edited) On my Granite I found this connector un plugged and would like to plug it back together. I would like to know what it does first.The EPDM module sits on the fire wall in the engine compartment next to steering column.There is an A... B... & C connector.The local Mack guys got me the Legend and the Diagram. The Legend shows A...B & C but the Diagram doesn't Show any of the A... B...or C connections....Regards Rob Edited March 22, 2014 by Norway Quote Link to comment https://www.bigmacktrucks.com/topic/35101-what-does-epdm-c-connector-power/ Share on other sites More sharing options...
Macktech689 Posted March 22, 2014 Share Posted March 22, 2014 I checked a schematic and it looks like the C connector powers the trailer ABS .
