There are two ways that you can do this:
1.From the ECU Cable, that's on the GMC, looking from the bottom of the wire harness clip, the 4th wire from the left bottom series of wires for negative, and the positive on the 2nd wire from the right hand side top series of wires.
2. attach wires from the tach from the negative side of the main branch of the coil pack positive wire, and negative to the negative wire.
Then after that's done it should work, depending if you need a power supply from battery or turn-key acc on wire.
