Hey there, long time lurker, first time poster.
I have an 03 Sequoia with two nearly dead cylinders (1 and 4, bummer) so I ordered up a used 02 Tundra engine (2uz) knowing it would fit. That said, looking at the wiring harness, there are some differences where the ECM is concerned. Essentially the sequoia has 6 different plugs going into the ECM and, I assume, the TCM, whereas the donor tundra engine has only 5. Like it's missing a whole slew of connections.
Have any of you run into this before? Should I be able to pull the harness from my Sequoia engine once it's off and swap it over to the Tundra donor? Or will I be missing some sensors?
Thanks in advance!
