Engine Swap Wiring: I need suggestions!, Wiring Gurus please have a look Options

Hey everyone,

I'm in the middle of an engine swap right now and I'm getting kind of confused. I understand that I need to strip out all of the engine related stuff from the recipient car's harness, which I've mostly done. All of the wires that ran from the ecu down the harness I've pulled/cut out. The thing is, a lot of wires ran from some of the body plugs to the ecu, and I cut those. Here is what's left of the harness at the interior end, you can see these 5 plugs that go into the locations in pic 2.

PIC 1


And this is where those 5 plugs go:

PIC 2


Now, here's the engine bay end of the harness, which shows the plugs that go to the fusebox, the positive battery cable, etc.

PIC 3


Here is the new engine's harness at the ECU end, I have not stripped anything out of this yet. You can see the two plugs on the left have been cut, all of these wires went into the dash on the donor car. The two plugs on the right go down the wiring harness, and there's another plug off to the right that plugs under the dash.

PIC 4


Now, am I right in thinking that I have to find homes for all of the wires in PIC 4 on the left that have been cut? Will those wires go to the wires that I see in PIC 1? And how do I go about putting these harnesses together?

Thanks a lot for the help

on the car there is an engine bay harness, an interrior harness, and a body harness. you only have to modify the engine bay harness.

basically, what you do is take the 3 or 4 plugs that go into the st185 fuse box and wire them into the lower part of you 6th gen box.

then rewire the 3 plugs that come off the engine bay harness into your ecu, the COR, and the 3 other interrior plugs that sit infront of the ecu. the only thing you really want to do custom at this point is to take the st185 fuel pump relay and add it right into the ecu.

I think he's talking about his 2ZZGE Swap. But those instructions are general enough that I'm sure it'll be figured out.

Man, doesn't life just suck. We need more info on the swap your doing!
we can't help you if you just tell us about the wires and where they go.
In most cases, get yourself a wiring diagram from chilton or something.

seriously dude, bringing back the dead......

No kidding, I'm like, what the....

This swap was completed months ago and I've done more since then. I am now TEH MAD TYTE L33T TOYOTA WIRING GURU MASTAR!!!!111one
