So, I just picked up a 91 turbo. I love it! It's going to be my winter snowmobile. The check engine light is on and I've read that I can check the codes and determine what is wrong. I found the directory of what the codes mean but I don't know which connectors under the dash to connect so it will go into diagnostic mode. Can anyone tell me which connectors to put together and the procedure for doing so? Thanks!!!

The black connectors will put the ecu in read mode.
