I need to connect to heaters 220v control thermostat is 22A. Inside corner the red wires on the thermo are to the line and load are the 2 black wires. I have the white wire connected to the heater red and the black to the black heater wire. Now I need to jump over to the other heater but the left end of the heater configuration is different than the right. Do I need to run a wire all the way to the right of the heater or is there a way to jump to the left side?
Thanks

OK, You are feeding one unit on the right end and the other at the left end.

You can feed at either end. The left is set up to accept the feed, while the opposite end is spliced.

Splice the two wires at the left end, break the splice at the right, and connect your feed to those two wires.
