The access pin #s are specified on the code link I posted for you..
The Blk [neg] will go to 1 and the Red will go to 16 [ pos] .. that powers the tool w/12v.. the odd color bananna goes to the pin # of the specific module you want to check for codes. That is why I had the ODD color bananna in the tool design..so you could not screw up
{ Red/Blk are usually pos/neg at a battery, so you can't get that confused either]
Your main concern on the tool is to make sure you have the LED correctly wired , as they are polarity sensitive.. you can test that by simply hooking it to 12v power .. if you have assbackwards, it won't light.
