I was quite tired of the wire clutter from having a laptop, power inverter and DSMLink in the car, So I went about cleaning up the mess. I decided that I could fit the 400w inverter behind the center console against the fire wall. I ended up taking the inverter apart to remove the on/off switch in order to relocate the switch to a more convenient location. I then purchased a 6' three prong extension cord, black electrical outlet, on/off switch, and a serial connector. I plugged the extension cord into one of the outlets on the inverter. I then ran the extension cord, switch extension and DSMLink serial cable to the rear of the center console. A hole was cut into the rear of the center console for the switch, serial plug and electrical outlet. I then hooked up all of the wire to the appropriate connection and put everything back together.
Now, I can turn the inverter on/off, plug the laptop computer into power and the ECU all from the rear of the center console. Clean.
