I ordered pack of resistors and am going to attempt soldering a 10k resistor inline to the dme on pin 19 and 20 and then run a 2.2k resistor from same pins on dme to ground which should give 82 percent reduction in swing. This was best I could piece together from diy on dp fix installs and how the procede v3 built in dp fix worked.
If interested lmk and I'll make new thread. Im sure wedge shouldn't mind the traffic to his but obviously he wouldn't want a full blown derail.
