About the 37 pin D submin, rather than introduce potential other
problems, i.e., more parts and the chance of a poor connection under a
screw head along with corrosion there (ask me about this) wouldn't it be
easier to use a 37 pin con with removable pins ? Just solder the wire
to the pins and then insert them. No miss matches, a better solder
joint using a pin holding device (alligator clip) and the ability to
swap pin locations if needed. A step forward, not back ??

That is probably easier but now you are only half done. The wires come out
of the 37 pin D submin in a random fashion while what you would like
to have is say the four coils on the first four pins, the four injectors
on the next four pins and so on and so on. I can understand why Tracy
designed it as he did in what appears to be a random fashion due
to the limitations of his computer PC board layout.
Basically it is a rats nest. Hard to trace and hard to trouble shoot.
The aux or secondary PC board will organize the wires into a logical
grouping.
An alternate way of doing it is layout a wire harness jig on
a large piece of plywood and bundle everything together.
That is the way it is done in cars. Takes extra time
to design and layout the jig.
BTW Mark do you have a PC board layout program?

Hi Paul,
I've been thinking about offering a service of pre-wiring EC2 cables.
I have over 40 years experience in the electronics field, so soldering
and cabling aren't challenging tasks for me. Besides making the first
cable is a lot more work than subsequent ones. I have the prototype
finished but need to go to the airport right now, so I will send some
photos tonight or tomorrow.
Too bad I didn't start a couple of weeks earlier. I would have been
glad to donate a cable for your testing.

Im sorry too Bob :)
What do you think of the idea for the aux secondary PC board?
