air bypass solenoid valve relay

Where is the air bypass solenoid valve relay located? .. . . . .My 3k warm up doesn't work and I would like to check this. The FSM shows what to check, but doesn't show where it is.

My service manual (86-88 N/A FC) shows the air bypass relay connector F-49 behind the right headlight below the air filter.

Page 50-32, 50-33.

Thanks .. . . Your comment made me realize there are more books out there . . .. Apparently this is the relay that controls the air bypass valve which aids in the 3k warm up. Not to be confused with the BACV that controls air when loads are added. .. .Now that I know where it is I can check it.

The fast start/AWS gives the motor fuel, and this gives it air apparently. . . ..I'm assuming. . . Just trying to make it run like it should.
