How to Install ALDL USB Cable on Windows and OBD Software

Most ALDL cables come with a CD (drivers) and installation instructions. Refer to their instructions first.
Otherwise, proceed to Step 2.
Download ALDL Cable Drivers here.
Then unextract the file anywhere on your computer.
Once you plug-in the cable into your computer — Windows Vista, 7, 8 will likely install drivers automatically. Without you having to do anything. In which case you can immediately connect other end to the car, load up the OBD software and start scanning/tuning.
Windows XP will ask you to specify/browse location of where drivers are found. Choose the same folder where you extracted drivers in STEP 2 above. It'll then install and you're all setup!
Go to Control Panel.
Expand "Other devices" or "Ports (COM & LPT)". Whichever contains "USB Serial Port".
Next to "USB Serial Port" — you'll see a number. Keep note of that number. EG: COM5.
You'll have to specify that inside OBD software, so that it can recognize the cable.
All that's left now is to plug the other end of ALDL cable to your cars port.
Launch OBD1 software like TOAD — specify within the software your ALDL COM port number (as per Step 4 above), and Connect!
Use this ALDL tester software to verify that your ALDL cable is recognized and properly installed to Windows.
It'll also tell you what COM port number (as discussed in Step 4 above), your ALDL cable is using.
