air fuel gauge

Supraman · 07-19-2006, 02:47 PM

I'm trying to install a air fuel mixture gauge in my 91 Supra Turbo. Does anyone know where to connect the gauge for the O2 sensor. Ive read that you can connect it to the diagonstic box but I do not know where precisely. I had hoped to connect it under the dash near the cpu. Anyone have any good suggestions. Thanks

which type did you buy,
i saw one that only needed to be connected to the o2 sensor and your good to go

Its a summit racing gauge it does say to connect to the o2 sensor. But I was hoping for something under the dash to splice into rather than under the hood . But I might not have a choice.

you can connect to vf in the diag box (02 feed)

edit: vf should also be at the ecu

Can you tell me if it would be marked at the ecu. Or maybe a color of the wire. Ive looked thru my chiltons and cant find it in the diagram.

looks like it's green w/ red stripe the VF wire
For reference the original toyota 1990 TSRM is located at http://cygnusx1.net/supra/library/TSRM/
don't bother with the chiltons lol
