I put the test light to C2/10 LB/OR wire by piercing the conductor insulation connector connected and it lit up.
Engine off or running. However with engine running, blower ON and AC light ON, test light not lit (Off).
So jumpering this wire to ground won't damage ECM?
Just want to be sure before doing so.
