Re: P&H Injector Interface

[romans@starstream.net (Romans, Mark)]

On the 165 and 730 ecm, batch fire, splicing at the ecm would be by far the
simplest solution.  Especially if it were done right, ie: plug and play with
correct connectors.  Since the environment is already as computer friendly
as a car is going to get, power, ground, injector leads are all right there.
I would also splice if necc to run P&H injectors.  Wouldn't be hard
especially with the batch fire set up.  Sequential would obviously be more
complex, but I would think much simpler at the ecm than at the injectors.
