89 4runner swap
I am finally venturing into my 3.4 swap. I have been reading everything I can for at least a year now also pm'd a few of the famous 3.4 swappers on here so I feel I can do this. The all to familiar wiring is still kind of confusing but I will slowly work threw it( asking alot more ?'s I am sure). I am having a hard time diving into the tear down of my girl she has always been there for me but now she is a little tired but if I call on her she is there. We hard a good ride tonight and it looks like this weekend I am going to the point of no return and pulling the 3.0 out. I have every every wire labeled except for the two body plugs which I can't locate a wiring diagram for those? but after I get the motor in I will worry about them. Thanks to everyone on here for all the tips and info to help the less knowledgable do these swaps.

I have a few questions on wiring if any of the great swappers could help me out with. I am using a 98 auto harness with a 96 manual ECM. There are a few wires I can't figure out. The 96 shows FPU ,ACV ,G-. It looks to me that FPU and ACV go to VSV's that are not on the 98. The G- looks like I could splice it into the NE - because on they go to the same place on the 98 but with separate wires. Any help would be appreciated.

Update
I got the motor in today. I am trying to figure out the rear coolant hoses tomorrow since my runner has rear heat. Also my fuel lines are both female fittings.

Black wire on fire wall
My 4 runner has a little black wire coming from the firewall that connected to the back of the 3.0 intake. It looks to be just a ground has anyone used it or connected it to your 3.4?

I have always upgraded the ground wire. Grab an 8ga. or larger to go from anywhere on the motor to the body, preferable the firewall. Where the 3.0 evap mounts is a good place since there is a threaded hole to accept a bolt rather than a screw.

If the engine was "installed" like factory with no additional power consuming electronics, why the need for larger ground wires? Shouldnt the factory ones be enough? Thanks

People do it as a preventative measure. If you search for "big three" then you should find why people were doing it. If I remember right, lights were fading and their radio was making weird noises. And I dont know if you have noticed but people like bigger, stronger things here. I know I will be doing the big three when I do my swap.

The motor is in runs good but idles a little high but not all vacuum lines hooked up yet. I am putting the finishing touches on this week. I need some advise on where to weld in the o2 sensors in. My 4runner car was removed by the previous owner. Also need advise on the trans wiring. I will post plugs that I am unsure of.

o2 placement
Thanks Deathcougar I have two o2 sensor set up.I know that one has to go right before the cat but the second I am unsure of how far from the first I should weld it in since I am not running a cat.Or does it even matter?
