I am trying to make a new data cable. All the references I have found include parts to dead links. I am trying to connect to a 1995 obd1 pcm with flashhack and eehack. Will this circuit board work and do I just need to connect the TX and rx terminals together and run that wire to the pcm along with a ground wire connected to that terminal?

If it would work what should the power jumper be set to, 3.3v or 5v?
I have successfully made the cable with this https://www.amazon.com/DSD-TECH-SH-U..._=sb_s_sparkle https://www.amazon.com/-/es/Akozon-P...tronics&sr=1-2
That should work, and the ALDL is a 5V Logic Level.Quote:

Nomakewan,
Thanks I'll give it a shot.
tx and rt must be connected to pin 9 of the 16-pin obd1 connector and the Black or GND Ground wire must go to pins 4 and 5 of the 16-pin obd1 connector
Comment on your results to help you if you have further questions
that's pretty much the same board i have. it'll work fine
just pin 5 would do, you don't need bothQuote:
