I recently got my 1uzfe swapped into an 82 Supra running. However, it won't rev last 4K RPM. I am guessing that means it is in limp mode. My problem is I can't check for any codes because the check engine light does come on at any point.

The current engine/wiring/ECU setup is- Engine is from a 95. Harness was originally a 95 but converted to run a 94 ECU.

Any help on where to start looking for why the CEL does comes on so I can check codes is appreciated.

Thanks!

Turns out I was just an idiot and was grounding the other side of my bulb rather than putting it to ignition switch on power. Made that change and it comes on perfectly.

Doesn't it feel good when you figure it out yourself.

You may feel silly for a minute but then you figure I've just learnt something.
