Ford F150 - 1992 F-150 Passenger Brake light / Turn Signal out

Howdy,

I just got a 1992 F-150 and I'm having some electrical problems.

Running lights work, But the passenger rear turn signal does not work, Neither does the brake light on that side.

So far I've replaced the bulb, the MFS (Multi Function Switch) and turn signal flasher unit.

I'm looking for suggestions as to what to check next.

Unrelated my temp gauge and oil pressure gauge also dont work.

I had a bad ground on mine . was fixed by replacing wire to a good ground. I agree about the gauges {unrelated} check gauge.
