Hi Paul, I would worry about using a breakout board, if that is what
 the picture shows, because wires are very prone to breaking under
 vibration when screwed down (even with soldered ends), if one was to use
 this type of connector, I would use the crimp-on pins then put under the
 screws. the Diyautotune cable bundle is 12 ft long by I think 37 wires,
 I did not use all of them because I dont have knock sensors, nitrous
 injection, idle speed control, ect. ect.

 Well that is why I am adding strain relief. I see no difference
 in clamp and crimp. NASA does not do solder any more. All crimp.
 Robin has a cute blond A&P Space Shuttle cockpit certified friend that
 teaches wiring at Sun & Fun. Her name is Marsha Buckingham.
 Look her up in the workshop areas at Sun & Fun and attend.

 I just found some bare copper wire coming out of an injector
 plug :) Where do I find some injector plugs with tinned
 plated copper wires pig tails? Just kidding.

I doubt NASA uses many screw down connectors.
I thought you were using the BO board as a temp test thing there's no
way I would put that in a plane, besides the fact it would not work in
my install, because of clearance issues.

The modern screw down terminal strip was invented after the space
shuttle was designed.

That board you see is not the final design. You will see the final
design next week. It will add little to the size of the EC2 or EC3.,
I would do a 3D but people can wait to see the part.
Then you can decide if you want to put it in your airplane or not.

You got my curiosity up Brian so I called my space shuttle mechanic
friend Marcia Buckingham. She said screw down terminal blocks were used all
over the shuttle. What they have is a tiny torque wrench that
is used to tighten the screws. Sort of a high buck screw driver.
No lock washers. All wires are crimped and not soldered.

After everything is assembled and tested a two part
RTV conformal coating is applied. There is some stuff sold in Fry's
and other electronic places  that is easier to apply and it is
similar. MG Chemicals Silicone Conformal Coating. This locks the
screw but is easy to over come for repairs. We use it to fix pin
hole leaks in the water jacket around p-port tubes. Basically it
is just clear liquid  silicone rubber.

I think if it is good enough for the space shuttle it should be
good enough for your airplane :)
