I am trying to figure out this wiring diagram and I am not sure what this test mode connector is. There is more than one and I know its not the OBD II test terminal. I hope someone can help

big scott is the only one i know that has wired his own obd2. not to put him on the spot but i bet he could help, also have you thought about calling enginewiring.com, they have always taken the time to answer my ?s even though i didnt use them for my own wiring harness.

Grounding that wire puts the ECU into Test Mode. Which is used for some more in-depth diagnostics, and to fully clear the codes.
