gotcha. Yeah this wiring has me pulling out hair haha! nothing else on the swap bothers me, and normally wiring doesnt bother me much...there is just so much of it on this lexus though!
Hey guys, starting my swap. Old drive train is out tackling the toyota wiring first while I wait on some engine mounts to come in the mail. I was looking at this diagram Vortec Swap - Pin Out Sheets and it seems like the old ECU/TCU(mines a 94 so it has both) has no functionality left at all and can be completely removed? Does that sound correct?

Do you have a and EWD for the Toyota? Sounds like no.

Yes
Thanks for confirming, a few of the T case wires also had split offs that when to the ECU. Wanted to make sure that the ECU didn't have any T case functionality rolled into it.
Looking at options for cooling. I want to go electric fans. Doner is an 05 Yukon Denali with an LQ9. I was thinking about ford Taurus fans or F body fans like other have mentioned before but then I found this. Seems like and easy option for the price. Anyone running one?

That's a little much for a radiator when so many people have run the stock one with success. That would be more than I have spent for the entire conversion so far.
I used a Steel Nutz unit that has been bulletproof since install and provides more than enough cooling. Not the cheapest but I’m happy I did....

Personally, I’m running mech fan, but I’d rather run f-body fans over those included with that rad.
The mounting points look different that stock, so the shroud I made which bolts on to the stock 1fz radiator wouldn’t bolt to that rad without modification.
If you get it let us know what you think. I’m kinda in the market for a new rad. I’d have to make a “Jon Davis” logo to sit on top tank for laughs when I pop the hood.
I have a Chinese aluminum radiator. Works really well actually. But I use a mechanical fan. That shround for the electric fans doesn't look deep enough to me though.
yes , all you need to hook toyota signal for ac clutch
for radiator i'm using stock radiator with mechanical GM fan i m running extreme duty fan clutch and with scoop on the hood my temperature is at 190-194 all the time
Thanks,
I have a 5.3 in my FJ40 and I'm running the stock GM mechanical fan but the donor truck for this project is a 2005, it had electtric fans stock and I wanted to try electric, it is always easier to go back to mechanical later. For those of you running the F body fans are they capable of 2 speed operation or are you just running them single speed?
2 speed. I. Wired it just like the factory using 3 aftermarket relays.

I installed 2006 E-fans on my 2001
This is a step-by-step tutorial on how to upgrade any 99-02 GMT800 truck or SUV to the 05-06 GMT800 electric cooling fans. This same setup can be used on 03-04 trucks as well, however, the only difference is the wiring that connects to the PCM. I will also add that a custom tune from someone...

Thanks, Any suggestion on year/make/model to steal the fans off of that fits best? early 2000's Camaro or something?
I used a dual fan setup out of a 2006 impala that I grabbed out of a UPull. They aren’t going to just drop in though.
Stock 80 series radiator?
