I have a plx m300 that im using with s300j on a jdm p72. Im using an obd2a-obd1 conversion harness also. What I did was run the power and ground directly off the conversion harness. I called up hondata and the tech there said not to run power and ground for <U>anything</U> off of what the ecu uses for power and ground. I personally dont see why it matters. I used the solder butt connectors they sell at napa and am recording .2 ohms resistance on each wire, about the same as before the wires were cut and soldered. The connection is clean and tight. My answer to the tech at hondata was "Wouldnt circuit will run in a parallel , so should it matter ?" And he just said "Trust me dont run anything off of there."

Has anyone done this ?
