My recommendation is to get a mid range digital meter meter that will permit the use of multiple probes.  You should get a unit that has the capability for contnuity testing.  That means some sort of buzzer, to tell you that the circuit is conducting electricity.  The digital meter should also display the resistance of the circuit at the same time.
 
One addition you will have to make is a 4 - 6 metre extention line for the probe.  This will let you attach the ground end at one end of the circuit being tested and then let you go to the part being tested.  For example, attach the one probe to a wire at the front dash and be able to attach the other end to the rear tail light.  The extension should be made of multistrand copper wire (coated of course).  You want a probe line that will carry sufficient current without significant internal resistance and voltage drop.  I prefer units that have replaceable fuses.  Yes, eventually everyone will blow a fuse or two...  nice to just replace the fuse, rather than the entire meter.
 
The probes used should have tips that can be removed and changed, depending on the circuit being worked on.  That will include shielded rubber boots, alligator clips and sharp needle probes.  No use creating more damage by grounding out other circuits while you work.
 
You next best friend is the correct wiring diagram for your vehicle/  That also assume the the Previous Owner (PO) documented any wiring changes in the Bentley manual for your vehicle.  I know that you will document all your wiring changes for the next owner.....
