No just one sender, Chased wires all the way up to the printed circuit board they all seem to be in the right place, If it had dummy lights before and changed out, would the tcs be eliminated? I have pos 12v to 4 of the wires to the plug that plugs into the pcb. not sure where the sender would get power from the circuit board to feed the gauge.

check the vacuum line coming off the distributor to see where it is connected. If directly to the intake manifold or carburetor the TCS system is gone. You cannt follow the wiring diagram in the manual back from the temperature sender?
