I appreciate the feedback. Marty - you are right - it is a challenge (and maybe stupid) - but I'm learning a lot and it's keeping me busy. I am well aware of the sensitivity of these PS3 boards, and the PS3/2 replacements, as I have had issues with two PS3/2 conversion kits already.
I decided to keep the original F3 motors and re-mount the tach board and I had spare 30mm tach tape from a steam conversion.
I'm going with the PS3 LEDs, driven from the PS3 board and ditching the CV board, as I can get all the lights I want from the GP20. There are extras that I don't need. However, as GRJ indicates, what I am missing is the MARS light wire from PS3 40 pin connector #35. I don't have the pins or insertion/extraction tools.
There are a couple items I don't think I need, so I could extract the pins from those locations and move them to the pin I need, if someone has guidance on how to do it without a fancy tool.
Or if there is a part number for a compatible pin (and recommendation on how to crimp without the right tool). Note I've seen GRJ's recommendation on a different thread for a cheap crimper for the larger pins - I'm probably willing to invest in something like that.
I know this is probably killing some of you - not using the right parts, not using the right tools, etc.
