New to the Land Cruiser world, and boy do I have questions.... OK, so my 94 was throwing a check engine light code. I have an older Innova scanner that is supposed to read OBD1 codes, but as luck would have it, I don't have a 16 to 22 pin adapter (since ordered one) but was able to use the paper clip "technology" to read the code. (bad O2 sensor) But here is the problem: I cannot find the OBD1 port under the dash, what am I missing? Can I use the port in the engine bay to connect to a scanner? However, if you will review the pics I attached to this thread, you will see three connectors hanging beside the steering column underneath
, what are these for? And in the next pic you will see two connectors just above the steering column, what are these for?
1994 FZJ80 OBD1 dilemma, a nub in need of advice.

There’s no port on obd1 trucks under the dash. The one you paper clip is the only diagnostic port on 93-94. Your scanner might work? The only two I know that work for sure is the toyocom scanner and a new zf-scan tools people have been using with a APP.

What do you need to scan just replace the 02 sensors.

89465-69115 That’s the part number for O2 sensors that work on the 93-94 rigs just replaced them on my 93.

Well, thats the internet for you, I googled the location and it stated that the OBD1 port was below the dash. The older scan tool I have is supposed to read OBD1 codes, but from what I hear you saying that the Innova will not read "Toyota", well heck. The more perplexing issue to me is what are all the unused plugs?

Umm, I did. The post was asking about the OBD1 for future reference.

FYI, the port you 'paperclipped' IS the OBD1 port ... in the engine bay next to the firewall on the passenger's side (I also have the 94 80 Series)
When I cleaned the O2 sensor plugs, my code went away.
That's where you plug in the electric turbocharger. Toyota was way ahead of its time.

In my case, both sensors had damaged or broken wires.

I'll be sure to jump on TEMU straight away and look for a brushless T6.

The FSM will not provide part numbers. You can find parts numbers from several online suppliers that have Toyota online parts for catalog/diagrams based upon the VIN you provide. Partsorq is one of those.

Welcome to the 80s,
If you can get a hold of TOYOBD1 (Toycom model), it can read codes but can't reset them. It also gives you ECT readings (a must) and everything off your ECU via bluetooth and it's apps.
