Here's one for the diagnostic/tuner experts: I have a laptop with Diacom loaded and a cable that has an ALDL connector/adaptor that fits OBDII. I'm wanting to connect to my 89 IROC and need the proper ALDL connector/adapter. The ALDL connector/adaptor needs to fit the car on one end (duh!) and on the other end it needs a 15 pin D connector to plug into the diacom cable. The current ALDL connector/adaptor that I have that fits the OBDII doesn't have a manufacturers name on it but it has the part number MT2500-46.
Can anyone out there point me in the right direction to be able to purchase the ALDL connector/adapter that I need?
Thanks!

 

The cable you seek is proprietary to Diacom. That is the only place to get one.
