But unless I misunderstood what he said, he has the same exact setup as me. A 3.57 board and a home made wiring harness (not factory) and no adapter harness.In Yates' case he had a plug-and-play version of Megasquirt for a Mustang, but did not have the adapter harness that normally comes with. The adapter harness has the required pull-up resistor for TFI, it is not internal to the plug-and-play computer. So he did not have computer controlled timing until he added that resistor.
There is no dedicated set of pads for adding the resistor - but you can put the resistor on top the board, wrap it in heat-shrink tubing, and connect one end to S12 and the other end to the center hole of Q16.So how could he have the pull up resistor? I thought the 3.57 board didn't have a spot available for it regardless if it was a PNP or not. Maybe I'm missing something here.
To your question, there was confusion in your case b/c you had a "plug and play" computer, so we all assumed everything would be in the computer itself. We later figured out that the plug and play aspect considered the cpu and the harness it comes with. They're sold together so that's not unreasonable.But unless I misunderstood what he said, he has the same exact setup as me.

Not attempting to ignore anything else you wrote, but if your engine will start with the spout in, but will not start with the spout out, this is the 800 pound gorilla that you need to take care of 1st.The car will not start with the spout connector disconnected.
Roger that. Not good that the negative side isn't pulsing. Just realized you have a '94. They have a different TFI than the foxbodies, and if you don't set up things right you can burn up coils and modules. Been there done that.lol yea no one likes a 800lb gorilla, I have no spark now the TFI seems to be dead :shakehead, there no spark to the coil and the negative side is not pulsing. I am going to get a new TFI and hall sensor for the distributor and am hoping that this has been a odd signal from either or that has been giving me the trouble, especially since I highly doubt that they have ever been changed and the car is a 1994.
