Engine Swap Cooling Issue Help!

I just finished swapping a 2.2 old one slipped timing, but either way, now I'm having a bizarre cooling issue, my coolant temp readout will read -11, Jump to 289, go back to 104 all within seconds, which I'm assuming is the coolant sensor(pretty sure I have the one from my blown motor I could swap, but also the hose going from the thermostat to the radiator is completely limp when the car is running, can squeeze it right down, not sure if that's normal, looking for some ideas. I'm getting a small leak from one smaller hose that looks like its coming from the bak of the thermostat going straight up and over.any help would be greatly appreciated

Debbuging stages. Is the thermostat in the car the one that came with the junkyard engine? Might be rusted shut.

Your erratic temp gauge must be a bad connection. Did you clean the coolant temperature sensor tab before plugging it in or too much in a hurry to get it going?

I'm honestly not sure, I gotta take a look at my motor it's at a buddies house, he did most the work I jumped in here and there, but I'm guessing the coolant sensor and the thermostat are from the junkyard motor, what can I use to clean the sensor tab? Just a basic electronics cleaner?

I use a small wire brush on my dremel tool then apply dielectric grease to keep moisture out. It slows the corrosion process.

Prior to installing the hose to the thermostat housing he should have pushed on the thermostat trap to make sure it was free.

Well I replaced the thermostat and once the car heated up the hose running from the thermostat to the radiator finally started holding fluid, thennnnnnn the hose com off the back of the thermostat housing going up and back towards the firewall devolved a hole and bam there goes all my fluid lol so now I have to replace that hose, but hopefully atleast my cooling problem is in order, I bought a new coolant sensor as well and hooked it up hoping to fix the crazy numbers it was throwing out but to no avail, same stuff going on, I looked at the connector that goes into it and it looked fine.. Very confused :/
