DIY OBD1 cable (USB) Build help please
Because I'm a little slow and ride the short buss more often than I like.....
I have a 1990 C1500 with a 5.7 and TBI. As far as I know nothing has been done to the engine or computer.
I want to take one of the dozen or more USB cables i have laying around and make a OBD1 cable so I can try to use the TunerPro software to do some data logging. That will be a whole 'nuther story! Anyway, which wires from the USB cable need to have connections crimped on them? I think there also needs to be a resistor some place? Where can I find that without spending a fortune. I'm in the wasteland of north central Iowa so everything I don't have will have to be ordered.
Thank you!
Ken
