THE 2ZRFE engine swap thread - Just the facts

Wiring for all swaps:

The MAF sensor does not get power from the harness, because there is no pin in the fusebox for this wire. There are two ways to deal with this.
1.)You will need to pop the black wire with silver spots out of the connector, or just snip it off, but I would lose my mind knowing a stub was there, lol.

You will need to use the mini add a circuit to provide a switched 12v+ supply to this wire.

2.) If you are going to use the ABS module to get your speed signal, then you will have two extra wires left from the sensor. A ground and 12v+ power. You could just use the power wire that went to the sensor for the MAF sensor. I am going to test this theory out and see how it pans out.

For the Yaris auto trans:
The xD does not provide a speed signal from its transmission so you have to move your speed sensor wires from the yaris harness/connector over to the xD harness/connector. Same holes are used, so no worries.
This is the speed sensor from the top of the Yaris trans:

The connector that goes on the sensor:

The harness bit on the old harness, you'll cut this open to get all the wire up to the white connector:

The three wires you will remove from the old connector:

I used a needle to get the pins to slide out, kinda tricky, but not to bad.

Their new home on the xD connector:

The order they need to go in:

On the auto you will also need to add a pin in upper connector in hole 9, next to the blue wire in location 10. This wire will need to be grounded to the transmission. The valve body in the yaris grounded itself to the ecm, but the xD harness does not provide that.
This is the connector and blue wire, in the picture it is the hole directly right of the solid blue wire.

The easiest way to achieve this, is to take one of the pin/wires out of the old yaris trans, remove the rubber plug on the xD connector, and pop the yaris wire in there. The just add an eyelet and ground it to the trans body itself.
The following picture is not correct, but will give you an idea of what it would look like. I was confused and cut the blue wire and grounded it. I should have left it alone, and added a wire and grounded it the same way. So do not cut the blue wire and ground it!

I will hopefully as some point try and get a better pic, of what it should look like, but it is really crowed in there and hard to get a clear shot. Soon though.

Yaris Manual trans:

I have not confirmed, but I am thinking the speed sensor would be the same wiring swap over deal.

Scion xD trans:

Okay so the ABS module will provide the signal for the speedometer. You will want to buy part number 82998-12720, or steal a wire from another harness. You will be putting this wire into location 4 on the ABS connector. It is the smaller white wire in the top row, four from the left counting the two bigger wires.

Then you can just cut the pink wire that went to the speed sensor and splice the new wire to that, making sure it goes to the connector in the fuse box.
