Gem module, is this mine?

I'm trying to install an overhead console, auto mirror and make a couple of other modifications that require taping into the Gem wiring,
I have looked at Griggs, How to;s and they are very informative, but the pic of the gem he uses as a reference, doen not look like what i have in that location.
I have a 2000 model 4x4 xlt.
Here's the image he references:

and what i have to the left of my stereo:

any help making sure I'm looking at the right thing would be great, I'd hate to tap in to the wrong wires, It;s bad enough i have a gaping hole in my headliner

Thanks,
Chris

Your GEM (AKA Central Timer Module) has 4 plug connectors instead of 2 like John's. The good news is that the gray/black speed sensor wire that John tapped for the console is also at your GEM. Just find it on the 18-pin connector and you should be able to wire it the same as John's instructions.

There are two different ABS systems in 2000 and the wiring for the speed sensor at the GEM is different for each ABS type..

RABS:
The speed sensor signal is output on the gray/black wire from your module. Tap the wire at pin #1 of the 18-pin connector.

4WABS:
The speed sensor signal is an input to the GEM instead of an output. Tap the gray/black at pin #9 of the 18 pin connector.

You should be able to use that wire as well (pin #8 of the 26-pin GEM connector). The 3 color codes at the radio harness taps should be OK, too.

Dang, my GEM was in the same spot but only have 1 set of wiring harness going into it. I thought they would be the same but I guess I am mistaken.
