Al,
I have the CK20, not sure if there similar or not, but in the fuse box are there fuses marked for 'customer use' and 'work light' ? If so there should be a plug on the left hand side at the back that has five pins in it. I can't remeber exactly what they all were, but I think without going to look that they were left signal, right signal, parklight, work light and ground. Also on the left side there was another plug (rectangular) with two pins, one was work light and the other was ground. On the right hand side at the back there were two wires together, a red and a black, the red being customer use and the black being ground. Not positive on which was which but it should be similar on CK30. If you find a wire with power on it, just try popping out the fuse that you think it is and it should disappear, this way you can prove which wire is which. One of this plugs had power with the key in the accessory position, the other when you went to thr run position. One thing about the CK20, it has a 50 amp altenator so theres no problem adding lights. I've added 220 watts (4 X 55W) to mine already with no problems at all. Hope this helps.
Steve
