'87 r10 wiring help

[jnickell41]

I have a couple of wiring issues on a new to me '87 r10 5.7L tbi.

I have found two loose wires in the engine bay, pictures attached. Tan/white wire appears to come out of the firewall near the steering column. Green wire is near firewall above driver side valve cover.

Also, when the headlight switch is on the passenger side blinker indicator in the dash stays on. When the headlight switch isn't on the blinkers/hazards appear to all be working properly. When the headlight switch is on the driver side works fine the passenger side blinks slower and only uses the dimmer of the two filaments. Should I be looking for an issue at the passenger side light, ground perhaps, or does this sound more like something at the headlight switch?

Thanks,
John
