[V8] Help it doesn't run!

[dsaad at icehouse.net]

I would just get the wiring diagram from the manual and verify against that.
If you plug in wires with the motor running you run the risk of a nasty shock,
and you also run the risk of shorting out the ignition coil. These hi-voltage
coils really hate to fire with no path to ground for the spark. The spark will
try its best to burn a hole in the insulation somewhere inside the coil causing
a total failure in the not so distant future.

If you want to crank the motor (for a compression test or something) always pull
the fuel pump relay to disable the ignition and fuel.

I learned that this is more than just theory when my friend crashed his
ultra-light for this exact reason. (he is OK but there were some scared bunnies
in the Idaho desert)
