Testing engine harness

Recommended Posts

Is there a section in manual

or anyone have schematic for the big gray harness next to passenger strut tower. I am trying to test it with multimeter to isolate problem or make sure before I go buy a new ecu. If anyone could point me in the right direction would appreciate it!

Checkout starting at page 5075 inthe 2005 manual
