I'm trying to get a oval throttle body to work on my 93 lightning. The stock three wires have a ground black wire, the oval has three wires but does not show ground. Will I need to ground the oval off the manifold or block to get it to work. The stock set up pressures up right way, the oval take 4/5 turns of the key to pressure up the fuel. Any help would be apreciated.
