heater blower wiring

[Biggy72]

When I got my car it didn't have a heater blower in it. So where are the wires for it supposed to be? I've looked all over in there and can't seem to find where they are. Also where does the blower bolt onto. I think I know, but I wanna make sure.

On a 72, the blower should bolt to a bracket that bolts to the top of the cooling fan shroud.

The wires come off of the relay board. I know this is for a 73, not a 72, but the board itself is unchanged.

On the 72, there is a green wire in the connector at the right-rear of the board. That powers the blower. There is a separate ground wire that winds up attaching to the ground point under the relay board.

where's this board at? is it the deal there on the drivers side of the engine compartment?

Yeah, that's the relay board.
