In the little diagnostic box up against the firewall. It says "diagnostic" on it, open the cap and look under there for the diagram to the terminals. The rest of the directions are on mkiv.com under tech articles.

are you OBD1 or OBD2? (if you are obd2... just go to autozone)

There's also a diagnostic port at the base of your steering wheel. Flip it open and there's a diagram of the terminals.

There's 2 on the Supra (at least on my car, 97 NA):
1. next to the hood release latch
2. under the engine on the passenger side next to the ABS unit or the cruise control

well which codes came up?
was 41 tps, got that problem figured out. now 31, maf sensor. I figure it wouldn't be fun if nothing bad ever happened. Also had 47 the sub tps, after I researched that I guess that kind of lives there since my trac control is disabled.

maybe the maf sensor needs to be cleaned? I read something about that on mkiv.com

Where - I haven't seen it on mkiv.com?
If you suspect the MAF, the simplest thing is to try a swap with a known good one (if you can find one around).
