This setup does work. Actually there are 4 wires (2 for power, ground and data). Bought a cigarette lighter adapter from radioshack and soldered the new power and ground wires. Since the new cigarette lighter plug has a rubber sleeve, I was able to drill it out to accommodate the zaon wire. All the connections are inside the lighter plug. The data wire then comes back out through the sleeve. Then I made a quick disconnect for the data wire going to the 496. Works out nice. I'll post a picture of the setup.
