When you installed the '81 which engine harness did you use?
The air flow switch is wired differently in the '77 than the '81.
The '77 has a brown with black single plug below the 14 pin connector at the fuse panel that is for the safety switch. The single wire female plug that goes to it, comes off the '77 engine harness just before the female 14 pin connector.
The safety switch wire in the '81 normally goes to the 2 wire "T" connector by the CDI box.
