Electrical Code reader

It has the right connections, but I would not buy it unless your OBD2 reader says it has the capability to do OBD1 testing. The systems are very different.
This is the nice OBD1 tool. There is one that has a led thst you count the blinks, and the method to use a jumper (paper clip) is posted on here.

The Q&A was not favorable. Even the seller says it won't work with just any OBD2 scanner.

Question: Will this work with any odb2 scanner?
Answer: no ,this will not work with any odb2 scanner

Probably not, the one I purchased wouldn't even connect with the scanner. No instructions either so if it only works with certain scanners, they don't tell you. Waste of money!
