Hey all. I want to install an Air/Fuel Ratio guage on my 86 9000 Turbo 5spd.

I am installing a custom boost guage, a Modded APC to red box spec, a 3.0 Bar FPR, Custom Exaust.

What are the procedures on installing this meter? I have never done it before. Kinda need some hand holding.
Awaiting replys
Much Appreciated! Thanks!

It depends on the air fuel gauge that you purchase and all I would suspect come with installation instructions. I have installed a few AutoMeter A/F gauges and have had 0 problems what so ever…..

I am thinking of leaving the Stock O2 alone and tap in another 02 for the A/FR. I heard the stock 02 has probs with A/FR's
