Line Lock
Disconnect battery.
The solenoid should have one end of it saying "IN"(female) use the supplied tubing to connect the "IN" (hole going into flat portion of solenoid the hole you can't see in the pic) directly to PoweMaster outlet connection. On most Master cylinders the front outlet goes to the front brakes. So connect the other end of supplied tubing where the tubing that went to the front brakes came out of .
Then connect original front brake tubing to the other end(outlet)of solenoid completing the circuit. Bleed brakes. Hook up your electrical lines. TEST ....Mount the solenoid on the drivers side fenderwellto where you can get to it and existing brake line can reach and thread in easily. Hook up all lines then figure out where you want to drill holes and mount.
Boost 231 commented on the switch, it does look a little funky. I would definately mount it where you can't accidently turn it on. That's the last thing you want is to trip it while your driving. Put it in a safe place.
If this does'nt make sense go to Summit type in line lock on search, then click on the Summit universal kit, when it comes up, on the lower left will be instructions click on it, the Summit system looked similar to your line loc.
You might want to disregard this and wait until someone who is more experienced responds. Just call Jack and I'm sure he can walk you thru it! Good Luck
