ahh i guess you're right, i forgot how it used to look.. that does make sense for routing
i deleted my level sensor and ran the maf ground to a chassis ground stud; so i forgot it used to be connected to those, there are no actual chassis ground pins running through my harness anymore
this wiring harness is hilarous, but i see where he went wrong now:
- he ran the ground stud to a dirty oil pan bolt, and had issues not having good ground
- decided.. screw it, lets just make a new ground harness so i know its ok
- pulled the two pcm/sensor ground pins instead of the chassis ones, leaving the sensor grounds disconnected completely
- ran the new chassis ground harness to the pcm/sensor ground pins
it felt so good putting it back together right!
