i have a 97 deville with a northstar. i need to know where the 3 ground wires are located. i actually know 2 of them but no the third. i know the one that goes from the coil packs to the block/head and also the negative battery that bolts to the block. the third one is the same length as the coil pack one. i have all data at work but its down there for some reason. thanks alot

Theres one in the rear of the motor (relative to the car) by the transmisions passenger side output shaft, another one on the front of the motor under the water pump where the motor bolts to the transmission, the little one from the coil pack to the rear head, one on the rear head near the transmision shifter arm, and the main battery cable ground on the front head.
