I am just getting around to wiring Tracy EFI/IGN computer
and I had an idea. Tracy uses a 37 pin D sub min male connector
that is rather hard to attach tiny wires to unless you are real good with
a tiny soldering iron or you have a special crimping tool.
This is a job I was not looking forward too as my eyesight
and hand coordination is not what it was when I was younger.

I was driving home from the hangar tonight and had an idea.
I have a whole bunch of these terminal strips left
over from another project and I had the idea of making a small
printed circuit board that would adapt a male 38 pin D sub min
printed circuit board connector to these easy to use terminal strips.
Merely strip the wire, insert it in the hole and tighten the screw.

I am laying out the PC board and will order a bunch of mating male
38 pin D sub min connectors to solder to the printed circuit adapter
board. If anybody wants such an adapter let me
know. Cost should be around $20 or $30.

I have these screw type terminals on my  Fuse Block With PTC chips.
I have had some loose terminals in 3 years. I suggest not useing the
screw terminals as you insert another connection to the circuit.

In every problem there is an opportunity. If the recess in the the top of the 
block where the screw goes is made square a drop of epoxy will act
as a mechanical lock with the slot in the screw. The epoxy can be pride
out with a small screw driver to release the wire for maintenance.
