Here is an old idea. I am thinking of making a new harness
  for the test engine. It is easier and quicker for me to
  do that than try to figure out what is wrong.

  Also it needs to be easier to do and better documented.
  We had one guy get so frustrated he ripped the rotary out and put
  in a Lycoming. He did a wonderful job on the installation up
  to that point. Real shame. It takes a highly skilled electronic
  technician to wire Tracy's EFI system and do it  well.

  I did not implement it at the time mainly because Bob White
  started making harnesses. Unfortunately Bob died of a heart attack
  about a year OK.


  I'll put the blinking lights on it so one can tell at a glance
  during started if anything is amiss.

  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 37 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
  37 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.

 Hello Paul,

 I'd be interested in the adapter.

 Ok here is what the PC board will look like.
 The PC board will be about an inch and a half high.

 The two rows of green 18 position connectors will be
 numbered in a straight forward fashion.

 1 to 19 with 2 missing and 20 to 37 none missing.
 One advantage of this approach the green connector will
 accommodate larger gauge wire for ground and power.

 I suggest buying jacketed cable and there will be pictures of
 that as I wire this system. One jacket will go to the
 injectors and one to the coils. That should keep things
 real neat.

 What type of coils are you going to use William?

I've got the LS1 corvette coils.

That is a good choice.

What is the part number William?

Do they look like this?

Do you have Tracy EC2 for the RX8 CAS or the old 13B CAS?
