wiring problems with mp5

my brother in law and i just dropped a new motor into his protege5 (same motor that was in before) a 2.0l 4 cyl we have had some issues but are close to being complete with the swap all thats left is an electrical plug that we cannot find any place where it goes, as you may or may not be able to tell by the pictures i am posting its a black plug with 2 wires coming out of it, a white wire with red stripes and a brown wire with red stripes and it runs into the harness by the intake. we have searched high and low for a place to plug this in with no luck, i was not there for the disconnect and a few things were forgotten about when labeling but please help, any wiring diagrams on pictures on where this could go, any kind of help is greatly appreciated

i believe that is the connector for the purge solenoid valve. The valve is located on the right side of the engine.

I'm 98% sure it plugs into the solenoid valve that sits on top of and is connected to the intake tube. I just changed my intake tube yesterday then went to check to verify. One fatter wire white with a red stripe and a thinner wire red (with some kinda stripe).

When you put on your intake tube that connector will fit right on.

The solenoid has two fatter vacuum lines on it.

Here's a youtube video for visual reference,... It's a 2000 Mazda protege 1.8 liter but our cars are almost exactly the same.
