Nilz90 Posted May 8, 2017 Share Posted May 8, 2017 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 Quote Link to post Share on other sites

Nilz90 Posted May 9, 2017 Author Share Posted May 9, 2017 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. Quote Link to post Share on other sites
