1993 4runner 3.0 diagnostic console
I would like to know what are the different terminals that I can jump in the diagnostic box to do different things, I know I can jump te1 and e1 to read engine and trans trouble codes but what else can I do??

Fp - B+ is the fuel pump.. That's pretty much all I know.. I'm willing to bet 4Crawler has a great chart explaining all the things you can do in there, haven't found it yet though..

Correction for the chart. Vf1 ranges from 0-5 v 2.5 meaning no correction at current rpm/load. 0 is ecm trying to remove fuel at 20ish %,1.5-2 is 10% ish, and vice versa. Handy for checking that new mods arent fighting the ecm.
This is just my research. Mostly from the supra forums

Trouble with Trouble Codes
When I try to jump te1 and e1, my check engine light does not flash at all, it just stays on. I have jumped these before and been able to pull codes, but now my check engine light is just staying on. I'm trying to pull codes because my check engine light just came on when my catalytic converter was glowing red after driving for only 30 minutes. Any ideas?
