Overhead console wiring from astrovan.

[Astro]

Hey all. I have an overhead console from an astrovan I'm modifying to fit my 96 extended cab sierra, but I'm a little confused about the trip computer/nav class 2 serial data wire. Where the heck do I tie that into? Also does anyone have any links to someone actually doing this? Thanks for any help.

I added a DIC from a s10 but they the same and you tap into the class 2 at data link connector

I've actually been parked on "How to" page for over a month. Just need to pick up some wire to install mine.

WE HAVE COME TO THE CONCLUSION THIS DOES NOT WORK ON DEISELS What you need. -DIC out of a blazer, a long console DIC has the compass built in -wire of your choice (I used 6 conductor phone wire) -temp sensor -I used 7 feet of wire from DIC to Radio I would suggest using about 8 feet -9 feet of...

Anybody do this to an 0411 swapped truck?

Not willing to swap it in if it's reported not to work, but would love to have it

What year do you have and which wires do we need to tap into?

I know 98+ work and I'd have to look through my diagrams for which wires

here is what i did. The stock obd2 plug has a wire that runs to the stock radio, and also has the class 2 data wire. Since I dont have a stock radio, i wired this wire to go to DIC class 2 wire and then i just stick a wire jumper in the obd2 port for the class 2 and old radio wire

Do you have pictures to help explain? Are you saying you don’t have to run any wires to the radio? Also, do you have mode or on/off DIC?

I have a 97 ext cab so that’s my concern
