I'm looking at a used unit on Ebay. The seller lists it as fitting my bike but he said he bought it used for his 2000 ZX9R and it didn't fit, which makes complete sense since his is the C model and mine is the B model. However, he sent me some pics of the harness plugs on the powerpak unit and one plug had eight pins, the other plug had 4 pins. He also said the plug with 8 pins only had 6 wires coming out and the smaller plug only had two wires. The problem is that on my bike the larger plug has eight pins but seven wires (one more than the six on the powerpak), the smaller plug on my bike has three wires where the powerpak only has two. Is it possible the powerpak uses less wires than factory CDI unit or is it the information incorrect. He says there is no clear model number on it.
