where are they both located on a 84 and what color is the wire that connects to the coolant sensor?

you NEED a shop manual

coolant sensors are usually found near the front of the intake manifold or on the cylinder head

Oxygen (O2) Sensor. Left side of engine, in exhaust pipe.
TPS (Throttle Position Sensor). Right side of throttle body at the front.
you really need a scan tool of some sort to work on corvettes

at about $140 its certainly affordable, but its basically a deluxe code reader

this seems to be a better deal, at $199

this is what I bought,(about $400) but mines several years old and theres even better ones out there now
BTW one frequently overlooked factor, in cooling your engine or adding an additional oil cooler, is your alternator size,in amps and wiring the alternator correctly, if your running a 70amp-100 amp stock alternator and using electric fans to cool the engine,its not going to provide the power required to spin the fans nearly fast enough to cool the engine like a better 200 amp alternator can

well i have a shop manual but its does not have a wiring diagram and i bought that same one you linked. so i dont know where the wire for the sensor is at but i will keep looking
