Peak and Holds in a '165

[Mike Pitts]

Make a circuit that has one injector driver for each injector.
That way none of the drivers will overload.  If using the 4/1
peak-n-hold, you can safely use one driver for each pair
of injectors.  For a batch system, all of these drivers can be
triggered by the original single driver's output. Since batch
fire timing is not important like SEFI, the slight delay added
(several microseconds proobably) won't affect a thing.

The harness has wires for the injectors and +12v.  The circuit
would have all the input and outputs it need is spliced in
where the injector harness plugs into the main engine harness.
