Wiring Air/Fuel Ratio Gauge and Boost Gauge

[Nilz90]

Hi,

I've got my dash out so wanted to know if anyone can help and advise on the best way to wire both these gauges.

Air/Fuel Ratio Gauge has 3 Wires Grey, Red and Black.

Boost Gauge has Yellow and Black Wire.

Thanks

your best getting the instruction manual.

The afr if compatible will have an analogue out signal, mine was yellow and I plumped it into the grey one on my e01.

Again instructions are the way

The gauges are Sard Racing, I don't have instructions as they came with the car but only the boost gauge was connected with the boost pipe and the rest of the wires we're hanging.
