Paper clips? Yeah they work, so does rubbing 2 sticks together to start a fire. Got 2 of these, (Ford & GM), back in the days of OBD-1, saved me a load of $$$. Paper clips?

I keep a paper clip and a code sheet in my glove box. Cost: Zip. Another vote for the paper clip for OBD-1. I keep a paper clip and a code sheet in my glove box. Cost: Zip.

Remove the dust cap, short these two terminals, put the key in run without starting the engine, then count the flashes on a lightbulb connected between these other two terminals. Took me about 2 minutes to scavenge enough alligator clip leads and an appropriate lightbulb. OBD-1 is even easier, since it uses the check-engine light. Short the terminals and count the flashes. I'm not sure why the "scanner" even has a built-in LED, except perhaps as a backup in case your check-engine light is burned out. Hit troublecodes.net to figure out what 12-12-12-61 means, and you're done! The pre-OBD interface on my ‘86 Renault did the same thing, except the contacts were under the hood.

That's all this does, but with a switch. Save yourself $25 and use a paperclip to short out the appropriate terminals on the ALDL (Assembly Line Diagnostic Link).
