Default Electrical ground and vacuum source locations

Do any of you know of 3 particularly good grounds?? Im not sure how to locate good grounds for my alky kit.
I also need another vacuum source to hook up the pressure switch. I used the one on the driver's side for the supercharger and boost gauge.
The kit I got has a pretty big external pump so Im still trying to figure out mounting specifics. Ive got a 2 qt container. Im thinking about mounting the bottle on the passenger firewall and then the pump horizontally on the metal piece above the passenger wheel well at the back corner of the engine bay.
I hope to get rolling on this soon.
Thanks

Any framerail or major structural member usually makes a good ground. If you have a continuity tester (ohmmeter) just connect one end to your battery negative, and one end to the possible ground point to test for a good place. It's easiest to use an existing bolt.You can buy crimp on ring terminals at an auto parts store. Crimp them on the wire, and attatch them to the bolt.

For the vacuum, theres a nipple on the passenger side of the intake that you can break off for a source.

Another ground option is the alternator bracket...it already has 2 bolts that you can use with ring terminals. It is definately a good ground since that is where you are supposed to put the Negative lead w/jumper cables.

As far as the tap for the pressure switch, I just inserted a "T" fitting in the line going to my boost guage. There are lots of places to do it, but since my pressure switch was mounted on the driver side bracket (by the hood hinge) it was just real easy to "T" the line. I can post pics if needed.

Yep, that's it with the hose attatched.
