FI is long gone and dash don’t work

Hey all.
Going to be bringing home my new (to me) '81 Imperial next week and I know I've got issues with it.
Some time in it's past a previous owner yanked the FI and put a 4-bbl on it (plus the Lean Burn got tossed for a Mopar electronic distributor and orange box). He had the presence of mind to label some of the wiring but didn't do this work with the digital dash in mind.
So now I have a running car with no gauges/speedo/etc. It all lights up but that's it.
I know I can just yank...
