<VV> Electrically Challenged

Rick,
    While I'd normally use a digital multimeter for this (DMM available for 
around $10 and up), you can use a simple 12 volt bulb with one lead connected 
to ground (any metal part of the dashboard/chassis/body) and the other lead as 
a test probe wire.  Check the terminals on the fuse block to see which ones 
illuminate the 12 v. bulb with the ignition key off and then with the ignition 
key on.  There are unused terminals on the fuse block that you can use for both 
of these purposes.  For the "on with lights" find the wire that goes to the 
parking/tail and instrument panel lights and tie into this one so you can 
illuminate your CD player at night.  Or you could use your console mounted 
voltmeter to indicate which fuse block terminals have power and which don't.(:-)
    Generally a DMM is a wise investment since it can be used for many other 
electrical troubleshooting problems such as not enough or too much voltage 
output from the alternator into the car's electrical system.  Ones that are made 
for automotive use frequently have an rpm setting enabling you to measure 
engine rpm under different conditions (such as setting idle speed).  They can also 
have a dwell setting so you can set your ignition points properly.
    Good luck,

I appear to be electrically challenged as well as mechanically challenged.  I 
am close to finishing the interior of my '65 Monza and have a few "loose 
wires" to deal with.  For the aftermarket CD player I need the following 
connections:
(1) +12v, always on, 
(2) +12v, on with ignition & assessory, 
(3) +12v, on with lights
For my new Westach console-mounted voltmeter I need a ground (this I can 
handle) and +12v (I assume with ignition on).
My question is:  Are there available spade connectors on the fuse block for 
these hook-ups and which are the best to use?  Is the fuse block not the best 
place to connect?
Suggestions will be greatly appreciated.
