I'm just trying to figure out where I got the whole idea that the '98+ cars have an additional data bus lead that 97 down doesn't have. It might just have been from what Aeroforce's documentation for general OBD-II equipment said (because the older cars need the separate turn-on wire for those gauges to work).

This is from my books. Wondering if maybe you guys can post or at least say if you have anything different at all in that 'Data Link Connector Diagnosis' circuit for 1996 and 1999. I guess 1995 is kind of irrelevant since it's OBD-I but if you have that, post away. I'm curious.

1997


1998

I'm just gonna start throwing stuff in here for reference as I try to unravel this.
My DLC has 8 wires going to it. Bold is what the aeroforce scan gauge actually uses. The fourth wire that they use I have to go back and find because I eliminated mine since my car does not support it. That's the one I'm most interested in right now but I also need to confirm whether or not hptuners/dhp uses any wires besides the basic stuff the aeroforce scangauge uses (so I can make my harness for them without leaving out any wires).

TAN [800] - UART serial data -- PCM,SDM,HVAC programmer,instrument cluster to EBTCM
PPL [1807] - CLASS 2 serial -- PCM,RFA module
ORN [40] - hot at all times power
BLK [150] - ground
BLK/WHT [451] - ground
DK GRN [835] - E&C serial -- HVAC programmer,radio
WHT [1787] - for magnasteer
other BLK [1455] - RFA (for programming keyless entry)

In this diagram, the actual pins that the aeroforce scangauge use are 5, 16, 2, 10


Pin 10 [J1850 bus (-) ] is empty in my DLC. This is primarily what I'm interested in knowing for certain if 98 or 99 rivs might have.

I hope one of these is what you're looking for... (96)

Thanks Matt! 96 looks to be exactly the same as 97. In my 97 book, they leave out the internal module circuit layouts but otherwise it's exactly the same. I so badly wish I had a techII and could communicate with all those other modules connected.

Now for 99...
Anyone with a 99 want to even just check your DLC to see if you have a pin at cavity 10 or just take a picture of it?

DHP uses the top connection for the cable to the DLC.


Here's the pin assignment for the AVT-84x DHP (don't see any J1850 bus - ) hmmm I'm starting to wonder if that is unrelated to the optional pin on the aeroforce gauge

I cannot save the picture for some reason. It comes up as MetaWeb Viewer...GM must've locked it out for some reason, but here's the DLC pinouts for a '99 Riv if it helps you at all.

Aeroforce Interceptor User Manual wrote:
This power wire is not needed on most vehicles.  The 2005-2007 Cobalt SS
and 2005-2006 Redline Ion require this connection, as do some early Ford
Powerstroke vehicles made from 1996-2000, as well as most Pontiacs made
from 1996-2003.   If the gauge is not turning on or off properly on these or
any vehicle, you can force it on and off at the proper time by removing the
small 2-pin jumper on the rear of the gauge and connecting the red wire to
switched 12v as described above.  



I just took another look at the user manual (for v2.8) from Aeroforce. It says that most Pontiacs from 96-03 need the added power wire (presumably meaning they would be missing pin10 on the DLC) so maybe I'm remembering the thing between 97 and 98 in error. They say the vehicles that need that turn on lead are in the minority though so I dunno. I gotta do some more research on the actual communication protocols.

what do you need? A pic of the 99 OBDII port?

Um...I put the '99 pin-outs up. Pin 10 is empty. Or am I missing something scratch
The pin layouts are in the same order as the others as far as pin #'s are concerned.

Yeah I just wanted to satiate my perverted fantasy of seeing deep into Zachs port
