HOLY BIRDS NEST BATMAN!!!!!
You're in deep Singtoe. Real deep. You've got some brass ones to go at a wiring job like that... either that or enough money to be indifferent towards failure.
That is what she said... :girl:
Nope, there is no option for failure. I am taking my time and making sure everything is wired correctly.
I thought about re pining my plugs but some of the plugs aren't the same, so their terminals aren't the same.
I am using crimped on butt connectors, and heat shrinking every one.
Toyota really has overdone the newer vehicles ECM's. The V8 Ecm is tied into the Airbag system, the tailights, the brake lights, body ecm, Traction control system and 4x4 ecm. All which the V6 ecm did not have provisions for.
Toyota did away with a seperate Cruise control ECM and integrated it into the motor ECM. So wires that were ran to the engine compartment now need to be run inside to the ECM.
I realize that, I can't program my key to the ECM because the ECM needs to sense the door closed signal from the body ECM, which I don't have hooked up.
The temporary fix is tape the sequoia key to the transponder amplifier. It has been working.
As for conversions, this has been the most intensive one that that I have done.
For the record, I have converted Dielsel VW's to gas, installed a EFI Mustang Motor into a S10 pick up, Gas Benz to a Diesel Benz, shoved a VR6 into a Golf, a 16v 2L into a Golf, and a Acura motor into a Civic.
So, I will not have any doubts in its reliability.

Youve got the experience there no doubt there, your attention to detail is also very good. I hope you documente from start to finish as there will be other that want to follow your lead. I just swapped a fresh 5VZFE in so I'm not a candidate for a couple years. What a great install................

Will do a more thorough write once done.
If there is one word off advice. Definitely remove the body. It made the conversion so easy. I did not have to maneuver the engine and tranny in a tight engine compartment. I read people have to uninstall and re-install their V8 several times before getting it right.
Pluses include not having to break the motor tranny up, banging the engine bay or motor, banging up my knuckles, sliding that heavy ass tanny and transfer case under the truck and up into the frame and dealing with the fabbing up an exhaust system from underneath.

I've got a 1" body lift on my 2002 and that was the only saving grace swapping in/out my re-built V6 in as there were 2-3 bolts on the bell housing that would have proved impossible otherwise. Sounds good, this is a far better swap than a Lexus 4.0L V-8, while more difficult than a supercharger the power would be worth itand longevity more likely!

I love this conversion. I am half way through wiring the Sequoia Instrument cluster into the 4runner.
The gauge fits but the tabs that screw it to the dashboard are in the wrong spot. I ground off all the tabs and used a radio back strap to fasten the cluster to the dash. Fits like a glove.
There is at least 50+ wires that need to be connected. I had to stop today because I ran out of terminals.
For every wire I connect, there is a deep satisfaction that comes over me and makes me smile. Kind of like when you snap a matching puzzle piece on a 500 ct puzzle.
I should have my cluster wired in tomorrow.

It's to bad the Sequoia fuel tank didn't go in as well, that is my only complaint about my 2002 4Runner is the range. I love the range of my 2005 Sequoia of course my dog, daughter, wife and me for that matter make it through a tank before having to stop.

Side note: Singtoe you might be interested in taking these projects on full time........figure once you have it ironed out it would take a week, and you could charge what the diesel swappers are 3-5K + motor+misc. parts soo $6k still cheaper than a diesel and you net 2-3 a week in labor......just saying, you need an assistant in NC?
