Default Intercooler reconnect boost sensors which wires?

Just making sure I hooked up the correct wires to the boost gauge sensor and to the overboost cut off switch. I have the green and brown striped wire going to the boost gauge switch and the yellowish/tan wire going to the overboost cut off switch. Is this correct? Maybe someone could post a photo for future reference to this question on the board.

TIA

Mark

Yes I believe this is correct.
I have forgotten to connect the pressure switch a few times, it's easy to tell, the car starts but stops after a second or so.

Can anyone else confirm this? As both switches emit boost pressure signals but function differently I don't think that mixing them up would be a good thing.

A little hard to tell .. so the brown and green wire is going to the boost gauge sensor (the orange thing)?

Trying to reconnect my wiring...

So the other wire coming out of that loom goes to the overboost switch. Then does a wire go from the other overboost switch pole to the intercooler ground?

TIA.

On my car the ground wire has a eyelet and screws to the side of the I/C.

I just went out and looked for you.

Tan-overboost switch. Make sure the connection is tight, you don't want that one working its way loose.

Brown and Green-Boost gauge sending unit (the big orange thing).

The other wire to the intercooler ground.

Man that intercooler does not want to sit down in there.

Just to make sure we are talking the same colors...
