As there are no proper wiring diagrams for the 2L-TE engine, I’ll try to bring some light in this dark issue, for those who are interested…
My engine is off a ’91 LJ78 Prado with AT , the engine and the related ECU wiring is similar to LN130 2L-TEs.
I’ve got the ‘naked’ engine with the ECU and the pure engine wiring without AC and Transmission wiring. With the wiring harness on a table and fragments of several different wiring diagrams I have made up the following list. The LX90 diagram comes pretty close to the LJ/LN wiring although it differs in connector / pin numbers and wire colours. But it gives a very good overview of the ECU wiring.
The list shows the Pin number, Pin code, wire colour and location.
