Need help finding a wire.

[6426yy]

Could someone tell me what color the wire is for the charge light bulb, in a 83 chevy with gauges.  I'm trying to wire in a CS130 alt and I'm not sure which wire I need for my sense wire.  My wiring has been butchered so hopefully I don't have to remove the gauges to figure this out.  I tried reading the diagrams but I couldn't make heads or tails from them.

Thanks
