Line Lock Solenoid question

Looking at picking up a line lock since I have my front brake system apart now, it will be easy to plumb. I was thinking of picking up the Summit solenoid and it has 1 inlet and 1 outlet. Other solenoids have 1 inlet and 2 or 3 outlets..

I plan on just locking the fronts and if Im mounting it between the MC and Dist. block. Placing it there will lock both front wheels correct? So I only need 1 in, 1 out, right?!?!

Or is there a better way to install it?
