Cat ID Or messenger display info

I installed it in my 98' 379. I got one from a local wrecking yard for arond $120. It was a smaller CAT ID with four buttons at the bottom. The harness was in the dash but connector in my truck was different than the one on the CAT ID so I went back to the wrecking yard got the connector and wired it to my truck harness. More than a year since and it works fine.

You can check behind your dash for a blue 5-wire connector. If it's there all you need a CAT ID and it is plug and play. If not the link above has the info how to wire the display into your truck.

 

When I installed one in my 97 379 it had a separate pair of curly wires with a data link label taped to it behind the dash above where you plug into it.
its very straight forward install, ground wire, keyed hot, data +,and data -
cat had sold me a extra harness to plug straight into the ecm that I didn't need. You would have had to find the right plug and install the pins, so you could go that way if you wanted to.
