Anyone know which wires go where for the OBDII port? My mother accidently ripped the port off and now I'm lost. Cant seem to find a proper diagram for what these wires even are, 2001 Honda Accord Coupe 2.3L.

Thank you this is extremely helpful. Now my conundrum. To me those 2 brown wires look identical. They are just brown with silver bands on them. How do i know which is which?

 

The Brn/Blk wire suppose to be have brown insulation with a black stripe running through it. Try to see if one of those brown wire has that.

Otherwise, the Brn/Blk wire comes from Ground G101. You can use a meter to test for continuity to ground.
