Hehehehe, the staff is still stuttering.

All the LEDs were flickering, and NO SMOKE.

Notes of interest, so far.

I wired LEDs as a visual indicator of the following Ign coil, Fuel Inj.
(for doing the 808/165 means 3), IAC (just 2), SES, TCC,

I'd figured to use a 555 for a ignition pulse generator, and fire a
LED for the having a 1.8v voltage to apply across the module,
as the reluctor signal.  Didn't work at first, turns out the input to
the module is polarity sensitive (when in this case being given a
pulsed D/C input rather than A/C).

I gotta tinker with some resistors and caps for my 500-8000 rpm
signal.
The 5K pots look to be a go for the MAP TPS CTS IAT (Thanks
GregP).

I might just use a divide by chip for VSS, and run it off the rpm
signal, and a double pole double trow switch for vss, and P/N
switch signals.

Lots yet to do on the 730 wire up, but will be a duplicate of what's
been done so far.

Bruce        Staffers are now wanting hazardous duty pay.  Maybe the
                  soft warm glow of the O-Scope will lull them into a better
                  mood...
