ajt49 just put it into 1st gear on 8thcivic
Relay shows its the Heating Conctrol unit to me.

Legs 1 and 2 are hot and ground respectively to the battery. Then leg 3 is always hot when key is in ignition on I or II and no power when ignition is off. The AC button can be on or off - no change in leg 3.
