You mostly will splice wires...

The following wires can be spliced from the non-digital DIC:

Left Door
Right Door
Rear-Left Door (if 4dr)
Rear-Right Door (if 4dr)
Trunk
Washer Fluid
Dimmer

If not a few more (it's been a while)

You'll have to wire into the VSS line to pull the Speed Data for the millage/oil/etc.

Search on Google for: Digital DIC conversion Grand Prix

I believe AutomotiveForums has the diagrams still:

question...

Does anyone know why I'm getting flashing zeros?

I've been searching and searching but couldn't find any viable solution.
I suspect that the data is not being supplied (or not correctly supplied), but at where is it not getting enough information?

I checked tan wire from DLC-9 and dark green from back of speedometer, they all check and are connected from their sources to the soldering point of the pins.

Even tried connecting scanner to the OBDII port and no codes, it does connect.

It's 98 GP GT, and the digital dic I bought off the ebay is supposed to be from 1999 GP as well.
(Does HUD have to be present by any chance??)

Any, I mean ANY, ideas please!!

I just got my DIC in off of ebay, and It didn't come with any wires or any wires attached to it. Will i need those? or is there a connector already in the dash somewhere for it? Any help is much appreciated!
