My (Stolen) PDF shows #40 ( White) is directly across from #30 (Blk) the Sensor Common wire. #39(Org/Blk) is one up from 40, and 38 (white) is one up from that. You have Two white wires on either side of the EGR Temp Sensor wire. I'd think if the Harness does not have an EGR Plug, you'd not have a wire on #39. My understanding is a 68K ohm resistor on 39 to 30 is needed to stop the code.
