MSD Blaster 2 wire help!!!

[SouthPaw74]

The wire pictured above broke off from the elbow connector on my intake. Tracing it back, it goes to a wire that connects to the MSD Blaster 2 coil. Not the red or black, but a third wire bundle (not sure of the color) that appears to go from the coil to a clip up near the firewall. Picture below shows in running into the other wires. Any suggestions on how to fix and what is needed to repair?

That looks like the temp sensor.
There is a 3 wire connector near back of engine that contains wires for temp sensor, oil pressure sensor, and 12v power to coil (on factory harness). Connector may have been cut off over the years. You can buy a pigtail to reconnect temp sensor.
