Aristo loom, supra gte engine: lambda and a/t power /normal select questions

[Pedroby]

Almost finished my ge --> gte supra engine swap with an aristo wiring loom.

But I still have two problems to solve Which I cant find an answer for online.

 

1: the engine is from a supra j spec GTE and the wiring loom is from a gte aristo. The aristo lambda sonde connector on the loom have 3 wires and the supra lambda on the engine has two.

I ve heard one wire is just for pre warming of the header, but can anybody tell me which one that is. And if I can just leave that useless wire loose or do i need to splice it with another wire. Or even do i need a lambda from an aristo to make it work fine.

 

2: the 40 pin connector pin18 is so called ' A/T normal / power mode select. I understand there is a button on the aristo to choose another gear mode to have a more sporty experience with longer and or higher revvy character.

Can I just leave this wire unconnected to another wire or do i need to splice it to amother wire from the gte engine/gearbox. The gearbox is from a gte supra as well. Would be interesting to have a sport mode, so can anybody please help me out with this.

 

Thanks in advance!
