Correct me if im wrong, but if i were to use a hk4/hk3 from viofo i can just splice the yellow cable to the white cable on the ecu plug?

Ok so for the hk4 from viofo, tapping the white wire does work. Just make sure the tap actually has continuity with both wires or it wont work. (Tap didnt cut the wire properly when pressing the metal thing in for me when I did it the first time around)
