120 ohms at Deutsch connector

[J_Rok]

Thanks to all for the replies on this, Rawze I found an earlier thread with a link to Amazon on which resistor to buy so I ordered that one. The confusing part here is that everything is still plugged in for the DEF tank, SCR and DPF in fact I can’t find anything unplugged. It could be a wiring issue I suppose, I did quite a bit of looking around and couldn’t find it but I might have to keep on looking. I just wish I could find the end of the network that’s supposed to be underneath the truck, would make it easier for me to troubleshoot. Truckdriven you be able to point me in the right direction as to what the main bulk head looks like at the DEF tank?
