OBD2 to OBD1 Port Adapter I have a 97 Z28 that was originally OBD2. I have converted it to OBD1 and need to know if there is an adapter that will allow me to use a 16 pin OBD1 (OBD1.5) cable with my OBD2 port. I'm tired of not being able to datalog for myself. Here is the cable I have:

I know there is an option to attach wires to certain pins, but I'd really rather a hard, plug-in adapter if there is one available. Thanks.

Here are a few thin to consider.
94-95 f-bodys had OBD1.5
I would use reliable source.
I don't know much about the sponsor only links here. SO I won't be posting links.
Just Google "moates ALDU1_CABL2"

I have no idea what you're talking about.
94 is OBD1 with an old school 12 pin OBD1 port.
95 is OBD1 with a 16 pin OBD2 style port. This is "OBD1.5" which really isn't any different from OBD1 except the connector.
96-97 is OBD2 with a 16 pin OBD2 port BUT the wiring harnesses from 95-97 should be the same despite the computer difference. You can swap the PCM to the 051 OBD1 model and a knock sensor in the block and that's all it takes to convert it to "OBD1.5."
There's no difference in datalogging/programming cable between 95-97. My friend has a 95Z and I have a converted 96Z. We both use the same 16 pin ALDL to USB cables and software.
I've tried ALDLcable.com's 16 pin cable. It worked for a little while (like 4-5 tunes flashed) and then quit mid tune and bricked a PCM. I also tried a cable by Red Devil River and had the exact same problem 4-5 flashes in (another PCM fried). I've heard nothing but good things about Moates and AKM (I don't think they're around anymore) so stay away from the cheap cables. PCMs aren't cheap.

So the USB to 95 OBD1 cable should work with my OBD2 port? Sounds like I might be doing something wrong.
Will there be any limitations on my ability to read diagnostics and datalog with that setup?

Just a little update. Tried it again on a computer that wasn't 10+ years old and free from my parents if I could fix it and everything worked fine. Connected great and logged about a minute of idle with no issues. Thanks for the replies.
