After consulting the DTA ECU wiring diagrams i know the proper pin connections for the serial cable i need to plug into it…

i’m using a serila adapter and emulating a serial port on the mac and trying to convince the win 98 virtual machine that it is a com port….
AND!

after some snipping and twiddling and soldering i have the correct lead

AND!

it works !

i can see all the diagnostic stuff and the maps and everything!
