i just got a profec A and was wondering if anyone knows what the back port on the box goes to. i looked on the greddy site and found where all 3 vaccum lines go to but where does the port on hte back of the box go. please help. thanks alot

 

does anyone know what the nipple on the back of the box is for?

 

do you mean on the bottom of the box?

(the one thats all by itself?)

it just gets left alone, its a vent to atmosphere... and should be pointing downwards.

 

thanks thats exactly what i was looking for

 

is all you have to wire up for the install is the red (power) and black (ground)??

 

yes, but the red is a switched power. (goes on with ignition)
