How exactly do you diode isolate the parking lights from the BCM?

This is quicker and easier.

Parking Lights + yellow (F), BROWN / white (R) + passenger junction block end of dash

you can save yourself the trouble of running a wire to the pass. side of the dash, by simply cutting the white wire coming out of the BCM, pink plug, pin A2. and placing a diode inline with that wire cathode (stripe side of diode) side facing the ecm plug, and tag your neg. trigger parking light from your source to the anode side of the diode. and your done, no need to run wire to pass. side of car. just did one yesterday actually.

Or you could just hit the blue (-) wire at the switch and be done with it. No cutting, relays, diodes, resistors needed.
