How to: Install DIC in gmt400 overhead console

[1997chevydriver]

Ok well after thinking about it I think I'd rather just have the temp/compass if the DIC is going to be off anyway. I wouldn't think any VSS input is needed, and I'd be fine with it being full illumination at all times, can't be too bright right?

It's not that bright at all.

I would think the ones with just the temp an compass only need power, ground temp input an illumination. Should be really easy to wire up. Mine is wwaayy of now with the big tires

Yeah thats what I'm thinking and it'd just be cool to have and useful with as much hunting as I do. What if I were to install the full featured one I have but only hook up the temp sender, power, and ground? You guys think it would work?

No you need the serial data wire no matter what on the full feature ones

Ya the temp an compass would work fine. You would just have extra screen to scroll through if you ever changed it. When you went to one of those screens it would just show --

I missed this thread, but here is some info on the consoles themselves.

Information on overhead consoles:

GMT400 trucks/SUVs used three styles of overhead consoles; A really short SUV style with only rear HVAC controls, and more commonly the longer console, in truck and an suv style. The truck style has a smaller opening in the front (same as the S-10s) and is much harder to find. The SUVs had a larger opening for HVAC contols. There are no options nor provisions for an OH console in a regular cab.

GMT800 trucks/SUVs used two consoles as well; a short console with only a pocket/HVAC and maplights, and an extremely simlar long console as the GMT400 SUV console. The short console is the most common, and is available in all models. The long console is not available in regular cabs.


GMT400 Truck console
The red console is in my 88 Sierra. It's the smaller opening style (shared with the S-10s). It has the compass/temp unit from an S-10 installed in it. The grey console came in my 99 from the factory, and I have since put homelink and a compass temp unit in it.

GMT400 SUV console / GMT800 long console.
This is the console in my 02 Sierra. It's the large opening style, and is actually from a GMT400 SUV. The only difference is there is a small gap on the back where it meets the headliner (which you can't see in the regular cab). I have a Denali Driver Information Center custom mounted in mine.

Color breakdowns:
GMT400 colors range 92-94 and 95-98 (00c). The 92-94 consoles also had a lighter metallic silver color for the plastic, as opposed to the grey color more commonly seen in 95-98 (00c) trucks. See the difference in the door on the blue console? Both of these were 92-94 consoles from suburbans.

GM800 colors range 99-02 and 03-06 (07c). Some 99-02 colors are interchangeable with 95-98 (00c) such as the medium grey in my 02.


Other Consoles:
S-Series & Astro/Savana consoles will not fit without modification to them, the rooflines are different. There are short, long (similar to a GMT400 truck console, but with a domelight at the back), and super long consoles from these vehicles.

The S-series also had 2 styles of computers available, a basic compass temp unit (with on/off and us/metric buttons) and an advanced one which does mileage (with mode and us/metric buttons). Both will fit in the GMT400 truck console. To use the mileage computer, the vehicle needs to be OBDII. I am unsure what vehicles they will work on, however know they are not compatible with 6.5L diesels and the mileage and range doesn't function on gas motors.
