1994 4runner 3.4 swap help
I started my 3.4 swap on my 4runner since the 3.0 finally bit the dust. A couple months ago i bought a wrecked 98 with a parts runner for the body panels and a couple other things but I still almost have a complete 4runner and I'm going to put the motor to good use in this 94.
My first question is could i just swap the entire wiring harness over from the 98 and run it throughout the dash and everything or would it be better to just wire it in another way. I'm not looking to spend a fortune on this swap so I'm using all the resources I have.
My next question is both my 94 and the 98 I'm using for the motor and wiring are automatics and I have a 5 speed and just about everything to do the swap but what do I do about the ecu and wiring?
My last question is the 98 I'm using for parts has a 2' body lift will it work in the 94 so I dont have to buy another body lift or cut a hole in the hood.
This is all the farther I am so far. Does anyone have any advice on doing this swap?
And I know to search for the questions I have but I couldnt find anything on a couple of them so I just put this all in one thread

Have you read through the 3.4 swap stickies ??
How are your wiring skills .
You just need to get the 4th plug for the 98 3.4 ECM and wire it up to the 94
Plus run the OBII connection
Pulling the whole dash apart to remove and install the harness is time consuming but an option.
There is way to make the ECM work with the 5 speed and a write up in the 3.4section
Not sure about the body lift But if they are just spacers I can`t see why it won`t work

Or you can pay ORS or TOS to create that conversion harness for you (to the tune of $400-600?).

Keep reading and searching, everything has been covered, but it's all scattered around the 3.4 swap forum.
