Your advice is well taken
For me Robert, I am happy right now. Been thinking of updating to an EBL Flash, or buying a Moates APU1' AutoProm Package. Both would have communication cables included....

Joined the forum just so I could say thank you Robert.
Built my ALDL OBD1 Cable for a grand total of $5.14.
Used the FT232RL USB To Serial Adapter you said you have been using recently...
