I replaced the cluster first thing after searching the forums but unfortunately the problem is deeper.

so you were not able to track down the trouble? or you did and figured out there is damage someplace inside the harness?
I just did it on my 98, and it fixed my issue. truck runs great again.
replaced the starter + engine harness. As

indicated you will need to remove the upper,lower intake to unhook the injectors. most of it is pretty straight forward but it took me several hours to get it all off without destroying anything.
also took me a couple of hours to get it all back on and some new intake gaskets along the way.
I got my harness from salvage place in rancho CA
Car-Part.com--Used Auto Parts Market
searched for engine wire wire harness
called the place and neggoated price a little. $250 with shipping to my door.
make sure you get the vin and make sure it's the correct part for you truck. your wire harness should have a part number on it up where it connects to the ECU. should look something like this
I think the part your after is
federal = 821213G311
California = 821213G341
California spec is the one for 2x catalytic convert trucks.
you should be able to find something like this one, not sure if this is the correct one but they are out there
2000 Toyota 4Runner Engine Wiring Harness-Stock# 180076
and one more thing... I did have to repair 2x connectors on the salvage harness. not a huge deal but depinning and swapping connectors can be a pain. the salvage guys can be a little angry when they remove things... just how it goes with salvage.
