My Jeep Grand Wagoneer has an AMC 360 engine with Ford Duraspark
ignition.  I don't want to try to get a Ford non-signature TFI
distributer to fit the engine.

Does anyone have any information on the signals input/output on the Ford
non-signature TFI distributer or the GM 7-Wire distributer?

Can the Ford TFI module or the GM 7-wire module be hooked to the relucter
in my existing Ford Duraspark ignition.

Does anyone have any information on the inputs/outputs of the distributer
connecter of the Holley Pro-Jection 4Di wiring harness?

What kind of spark control signal is output by the Holley ECU?  Does it
actually send out pulses that are intended to trigger the ignition, or
does it send out a signal that instructs the ignition where to set the
timing?

If you have any graphics files (wiring diagrams or whatever), please send
them to ray at sslinfo.com (My Juno account can't receive image files).
