I am about to purchase a jdm 3vze and it comes with everything except the ecu (the engines computer). I was wondering if it would be a problem to use the one off the truck being that these toyota 3.0's seem to have slight differences between each year. Like that temperature sensor groupings at the rear, I know have changed up a few times from 88-95.
So in short will it be a good idea and use a 90 3vze ecu on any other year 3vze engine?

When swapping the motors , use your set up ; ECU , Wireing harness , Sensors. In short use your new motor as a long block .

i have a jdm 3.0 in my '88 runner. take corbit's advice. the long block is the same. use your existing parts with the new motor, including the oil pan. you can use your current ecu with the jdm 3vze as long as you use your existing wire harness.

does anyone know if a jdm wire harness plugs will fit in a 4runner from the states? And do i need to get a jdm ecu because its a jdm mtor?

I just took a 3.0 out of a 95 runner with Auto and put into my 94 manual trans. everything is hooked up except for some of the plugs for the tranny, transfer case and O2 sensor. I didn't get the ECM from the 95 Auto so i am using the one out of the original truck. My problem is that the starter is not engaging. Just makes a ping (click) when i turn the key. There is a plug at the bottom of my starter with nothing in it and i can't seem to find anything off the new or old wiring harness that goes into it.

Does this sound like a grounding or relay problem?

Does anyone know what that plug on the bottom of the starter is for? I know the power supply is hooked up right cause i'm using the starter from the original truck and it was never disconnected.

Should i have gotten the ECU from the Auto Truck even though mine is a manual?

I hope i don't have to take my engine apart to switch to my or wiring harness...
