PS
If you do get the tool constructed , the hook-up is :
Red bananna [+ ] goes to pin #16 [ 12v power]
Blk Bananna [-] goes to pin #1 [ ground]
Odd colored bananna goes to which ever pin #/module you are extracting codes from [ in your case , pin #14 for EA/CC and #8 for HFM.......]
When you get these , post your findings and I or someone else will tell you what these codes signify/ indicate
