S13 SR wiring help - battery tray/02

[Touring240]

I'm posting this for a friend. krazy91 on northwestnissans.comHe and I are doing a redtop sr20det 5 speed into 89 240sx auto. (converting to 5 speed)

Ok I did exactly what heavythrottle's site about the battery tray wiring said it wasnt to hard, Im only unsure about 1 thing

It says that on HT's site in the battery area wiring.

"NEW INFO:

1) The brown wire on SR plug F10 needs 12volt switched to power the O2 sensor. "

I know what wire this is on the SR plug but Im unsure where its supposed to go? If anyone knows this would help alot.

thanks

You can run it off of anything that turns on when the car is in the "on" postion. Ignition +12 is on the same diagram..
