As you can see, both wires with white are ground and connect to the same point in the circuit. Here is a diagram of how I have my cable wired up to the TechEdge schematic. See the WinALDL page for more information about connecting to other vehicles. From the TechEdge documentation, I believe it should work with any 160 or 8192 baud datastream, though I have not tested it with any other vehicles. I have successfully used this cable with DM 0D on my S-10, and with DM TT and FreeScan on my Syclone. Only one needs to be hooked up, though connecting both won't cause any problems. Both ground wires run to the same place in the conversion circuit. Using ground from the ligher socket and a single wire for ALDL data is easiest, though grounding the second wire of the ALDL end (not pictured) at the ALDL connector itself may be easier for permanent installations, with only the power wire running elsewhere. There is a ground wire in each end of the cable. If you do try this, please let me know how it turns out. If you want to give it a shot, it's probably best to test it on any laptop you plan to use before snipping the lighter plug off. I don't believe this is a standard, so it may or may not work on your specific laptop.

It's stated on the WinALDL page linked below that some computers will supply power on one of the serial pins. The cigarette lighter is the easiest way to do this, although running the wire to a different power source may work better for permanent installations. The circuit needs 12V to operate, so a hot power source is needed. I am using their "two transistor sneak preview" circuit.Įxternally, the cable consists of a DB9 connector with a CAT3 phone wire splitting into ALDL wires at one end, and a cigarette lighter plug at the other. Details, including the schematic, can be found at TechEdge. This is a cable I made to use to monitor my Syclone with DataMaster and FreeScan.
