I've tried to get the diagnostic codes out of that connector near the battery from pin 7 but every time I plug it in to test things out I blow fuse 7 (climate control). I've only tried it 2x both times with the ignition on and 1x with climate control off 1x with climate control on (A/C). Is this the right pin? I've used the LED diagnostic tool before on other pins so I know how to connect it and work it properly. Thanks!
