[T2] Turn signals/emergency flashers 1971 bus

[Bob Pratt]

Hi all,
I forgot to wish everyone a happy and prosperous new year. I'm STILL having problems with the turn signals/emergency flashers. 

As per Bentley, I conducted a conductivity test on the turn signal switch and the the test showed the switch was OK. SO... The only other thing left, I think, is the flasher relay.

Because I confuse easily, is the correct relay the black box or the silver one. 

Also, the oil pressure light does not work. I've changed the switch and made sure the blue/green wire was not broken. Does anyone have any suggestions on what to do next?

I'm on the verge of just buying a whole new wiring harness and change every wire in the bus.
