1G Tach and diagnostic port stopped working

[LV-DSM]

I recently took my dash apart to clear out a dozen or so dead mice from my blower basket. Since putting everything back together, my diagnostic port, tach, temp and gas gauge have all stopped working. Blower isn't working either. The oil light is now stuck on as well. I've checked tach and data outputs on the ecu and everything reads correct. Is there a ground a forgot to connect? I can't figure out what ties all of these things together. Any recommendations?

Ground probably not, wires could be shorted or possibly damaged.

I would go back and inspect all the wiring since there were mice in there. How long has the car been sitting? Mice will chew anything.

Mice (and rats) chew on wires. I would almost bet they had a nibble somewhere. Maybe a power wire (they seem attracted to them for some reason) or a ground or more than one. They got under the hood of my #'s Matching 1987 IROC Convertible and chewed up 6 wires that I have FOUND so far but it killed the car until I find them all and repair them. Its a bummer. Hope that isn't your issue......

Check to make sure you have good connections at the junction block in the driver-side kick panel, particularly the 18-pin C-45 Instrument Panel Wiring Harness and Junction Block Combination, 8-pin C-54 Body Wiring Harness and Junction Block Combination, and D-05 and D-06 the connections for the gauge cluster.
