New here and really need some help. 89 c112 Cummins L10-240F VIN 442478. drove this truck nearly 150 miles home with the warning bells sounding and no gauges as nothing was hooked up. Only the starter and one wire to alternator connected. All the wires are there and I've been trying to chase each one and I'm about to give up. Can someone help me locate a diagram showing the wire numbers and location. This would be a life saver for this truck. Any suggestions would be appreciated. This is a waste oil vac truck with a 4000 gallon tank.
