You posted in the wrong forum so your post has been moved to the Chrysler Non-Specific forum.

What did you find for the GM?

i found that you can make a OBD1 connector for GM to read live data streaming of codes and what not i guess but why is it only offered for GM vehicles but not say chrsyler?

i wanna be able to reset transmission codes and find out if the solinodes are working
