How to retrieve codes on a 90 lexus es 250

[Comebackkid]

Don't have the tool so looking for info on doing the wire trick to retrieve the codes. How do I do it.. I see the diagnostic port under the hood :dumb:

Embarrassed to say I haven't done this yet myself. Im not sure if you want the one under the hood or the one under the drivers side dash.

I use the 2nd link to perform the diagnostic code reading on my Supra. Fuckin easy, peasy. When I'm done and want to reset the ecu/codes, I just pull the EFI fuse for half a minute. Actually, it probably says that in the link, too.
