At the top of the motor by the fire wall is a connector that leads 3 wires down to the trans and a black wire with plug that o have noooo ideas where to plug in. Now I have string reason to believe this black wire is the neutral safety ground, but I have a manual transmission. So do I need this wire, if so where would it plug in factory? Or should I jus cut the end off and ground it else where?
Work hard, Play hard. Jeep harder
Dunno about that wire, but there isn't a neutral safety ground.
Auto systems have positive and negative polarity period.
On the American side of the pond, the negative polarity is connected to the body and is considered "ground" It is usually black, but don't count on that for any given connection... particularly since a lot of connections just go to the nearest chassis to pick up negative polarity or ground.
