How to ground PDC?

LOL, I'm not going to blame you if it doesn't work! I am looking to get a OEM so I don't have to change it often. I'm looking on ebay right now, some SCAM OEM parts out of New Jersey on Ebay, $14 OEM CPS, no way this is legit. Geez, who can you trust to buy a OEM from? Dealer only? Geez.
Update: OEM Crank Pos Sensors are on 2 month backorder so I installed a new Cam Pos Sensor and trans no longer bucks when driving. Still stalls when stop and put in park, may try aftermarket crank sensor, also second guessing the idle control sensor I got off ebay, might be a counterfeit OEM.
