FC Vert Build. Need help I.D connectors and check valve
 

I am building up an 90 FC S5 but i do not know what the previous owner did with this checkvalve as i do not see it in any diagrams. I i need to know where the connector on the right goes to. the one on the left is for the Waterhouseing.

Thanks in advance

Both of those connectors go to the back of the water pump housing the round connector is just below the square green connector

Well i dont have that connector on the back of my housing. looks like it was blocked off.

I guess i posted this on the wrong section.

I believe it is a connector for an auxiliary fan (sender on the back of the water pump.)
No big deal if you do not hook it up.

That's what I though. Thanks
