Default Heater fan wiring

I have an 81 with all new heater/A/C components.

It all seems to be working well, including the fan running all the time.

I read in earlier posts that a brown wire can be removed from the plug on the relay on the firewall under the hood on the passenger side, but my car doesn't have a brown wire.

Could someone tell me which wire to remove from the plug to turn off the low fan running all the time?

If memory serves, the brown wire is in the connector to the fan switch and not under the hood.

Looks like you can delete the brown wire from the resistor pack, you will only have 2 speeds, but it will shut off.

I bent the terminal for the brown wire down and put the plug back on, and none of the settings worked.

When I put it back up, it works normally. It appears the brown wire is power for the entire system.
