Default Is this interrupt configuration on Cobb BSC?

Hi all. I am being tuned by Will at PD. He suggested I get a 3 port EBCS. I bought a Cobb and while looking at the installation instructions it does not specifically say "interrupt" and I want to make sure this is the correct diagram before I install and take the car out for a datalog.

Yes if the #2 is the common port, #3 is NO and #1 is NC.

Having the BPV in the picture is a bit confusing has it is 2 separated device....

Keep your hose as short as possible and using the bottom port instead of the top permit the use of a larger hose too.

Thanks for the reply.

Cobb does not have the ports labeled, but I think this is correct, I did email cobb today but I have not heard back yet.

you can confirm it by checking where the air pass thru.

Common into Normally Open (NO) should be open without power (normal state)
Common into Normally closed (NC) would become open when 12v is applied. (with 12v, the NO would be blocked)

just be careful not to mix common and NO because it will still seem to work with a bad response.
