instruments for 1989 with 72 engine

i recently had a my 4-banger pulled to drop an old 302. buddy never hooked up the gauges and is charging me a ridiculous amount to have it done. im mechanically oriented but not enough for this kind of conversion. im sure its easy but i cant find anything on the subject to guide me. speedo, tach, thermo, fuel, power, and oil arent working. the amp light and the backlighting all work as the a/c and indoor lights.

Speedo just runs off the trans. Tach runs off the coil. Thermo runs off of coolant temp. Fuel runs off of sender from fuel tank. Power/Voltage... cant remember this 1 lol, I wired my car over a year ago. Oil pressure guage works off of oil sending unit.

Get a Haynes manual, if will show you wiring diagrams ect on how everything is supposed to be stock. When you swap in a different motor and wish to reuse the stock guages then they need to be run just like they where before the swap.
