im looking for S106 splice on 2000 ford F450 7.3 and the G102 grounding spot
As a heavy-duty diesel mechanic based in Oregon, I work on a variety of vehicles, including F-150s, tractor-trailers, RVs, pumper trailers, wood chippers, and whatever else the owner brings in.
Best I have for G102 is left side of fire wall. The splice should not be far from there.
Unfortunately shop key won't give me anymore details than that.
You may have better luck buying a service information subscription from Ford for a few days if you still cannot locate the splice or ground.
