[DeTomaso] Duraspark I

Yes, with the newest module we just plugged it in and it worked. The red and white wires still change position across the plug as did the original. What has me asking is that all of the wiring diagrams I have found, and they are many, show that power from the run post on the ignition switch is connected to the red wire into the module. Did Ford make a mistake in the diagrams and fixed it by swpping the wires at the connector plug or what?

Are you saying that with the newest module, you just took it out of the box,
and plugged it in without any jumpers or wire swapping?
If so, why did the first new one you had not work unless you used a jumper?
It would not surprise me that they simply did not follow the colour of the
wires.  As long as the wire connects to the correct component inside the
module, and the indexing on the connector is correct, it really does not
matter what colour the wires are from the plug to the module.
Sometimes the modules fit many different models, and, sometimes the wiring
is of a different colour.  The connector is indexed to insure correct
hookup.

I've got a question regarding the duraspark I wiring. All the diagrams I
have seen show that power from the run post on the ignition switch comes in
on the red wire and power from the start circuit comes in on the white wire.
In trouble shooting a system today we had power on the red wire and power on
the white wire as noted above at the connector feeding the module but the
engine would not start. We then noticed that the red wire actually connects
to the white wire on the module and the white to red (male side of plug
reverse of female side). By disconnecting the plug and installing a jumper
from red to red the engine fired up. The first thought was that the NEW
module had the wires in the plug installed incorrectly. Comparing the new to
the old however shows that it also reversed the wire colors across the plug.
Since the car ran for years with the old module it did not seem prudent to
cut and change the wires. We opened yet another new module and it  also
reverses the red and white wires across the plug. We went ahead and hooked
up the newest module and the car fired right up with the red power wire
connected to the white wire into the module. 
I guess we should not fix it since this is the way it has worked for years
but why would Ford reverse the wires? Even in the Ford wiring diagram it
shows the run power connected to the red input.
Would like to hear from anyone who has any insight.
