I did something similar to what Scarceller did here:

I soldered new pick-ups directly to the DME unit for system ground (pin 5), RPM (pin 21) and simulated narrowband O2 (pin 24). You can also easily take your RPM signal right off the back of your tachometer. I added a molex connector to make removal of the DME easy for any servicing, etc.
Alan didn't have a long enough cable for the O2 sensor so I extended it myself and soldered it directly to the PCB in the wideband unit to minimize the splices required.
Only drawback is that the internal memory gets overwritten each time it's used. It would be nice to be able to store multiple sessions. Still a great product for the price. I can take a photo of the unit installed tomorrow if you like.
Total cost was $275 (CAN $ if I recall correctly).
