Trouble shooting the hitch wiring, found a fuse was pulled from the right turn signal in the inside fuse panel. I think 5, 6 & 7 were all missing. 6 is supposed to be blank, 5 is DLC & 7 was right signal to hitch.

#5 Data Link Connector DLC 10A is empty

What does this do? I assume I should put a new fuse in.

If it's the OBII (?) plug, I have my Scangauge plugged into it & reading just fine...

 

DLC is the OBDII connector...pin 16 should be power. I admit to knowing nothing about your scangauge so I cannot comment on how or why it is working.

 

Hummmm, interesting. I assume it works like any code reader, I plug it in under the dash, it tells me any codes, but then can be programmed to give other data, like mph, rpm, mpg, etc.

 

OK, got to look at it better today, 5 & 6 are empty slots, as in no metal recipetical to plug a fuse into anyway.

So not sure where the ODBII port gets power from, but it's not #6 as in the manual!
