Re: Where do these Relays bolt up? 71 A/C heater system
on mine the one with the 2 holes goes on the right side of the heater core box where i drew the arrow. I dont have the other one best i can remember, if im not wrong it is the blower motor relay and looks like someone might have took one off something else and spliced it in and used it instead. i could be wrong tho.

The other one may be the horn relay

I think the other one may be an anti-dieseling relay. My '71 has it. It mounts to the lower inside lip of the dash sheetmetal.

Here are some pictures to help get ya heading in the right direction, the four wire relay is your A/C blower relay and mounts just above the pass. side kick/footwell area. The three wire relay is your anti-dieseling relay which was a 71 deal only (iirc) and it mounts to the lower inner dash lip like member octane already mentioned above. Mel
