TCS has exciter rings and extra sensors other that the one in the main "hog head" of the differential.

It will work fine.

You can swap no problem. TC rear ends have the abs sensors near the wheels. Non TC cars have the abs sensor in the pumpkin.

just plug it up to the stock location.

It will not affect speedo because it is a wheel speed sensor and not a vehicle speed sensor

Your speedo is driven by the computer that gets its input from a sensor in the transmission. You really need a rear with matching abs/tc options to have your abs work. It can be done but would be spendy

i cant plug it back in because the sensors are in different places, my stock one was in the pumpkin and the one i have now is by the wheels and i dont have the wires or connectors to hook it up. and now my speedometer is way off after i changed rear ends, so do i just take it to get it recalibrated to work properly?

Correct

what about the abs sensors, where do i get the wires and connectors to hook that up since its different?

you don't,it's a different system/circuit.In order for everything to work properly,a 3 channel rearend should only be replaced by another 3 channel rearend.
