Installation: DIY Alky Injection

LEFT: This is the Hobbs Switch I used to turn on the pump at any desired boost level.  It is adjustable, I have it coming on around 12-13psi of boost.  Basically, it interupts the ground circuit of the pump until 12-13psi of boost is reached.  When this is reached the contacts close and the pump turns on injecting the alcohol into the up-pipe.  As you can see in the picture, I just tapped it into the boost line on the passenger side fender-well with a vacuum tee.

RIGHT: This picture shows the new coolant/alcohol reservior and the ground for the pump on the inner fender.  This ground goes to the normally open side of the Hobbs Switch, and when the switch is closed, it completes the ground circuit for the pump.  And yes, of course, I used wire loom on this part too.

LEFT: This is a shot of the battery tray on the inner fender-well.  The wires you see are the positive and negative leads coming up through a factory hole in the fender-well.  Th?ey come up just on the backside of the battery.

RIGHT: This picture is with the battery installed and all the wires back on the battery.  If you look closely, you can see the computer wire, and one of my two fuses on the positive wire for the pump.  This wire runs all the way around the back of the engine bay to the back of the alternator.  I was going to use the battery for the positive power to the pump, but decided that alternator voltage would be better.  *Thanks Razor* :)
