Well, I just got my car back from the local performance shop [actual performance shop]. I had them install my WOT Modified A/F gauge, boost gauge, and temp gauge into my pillar pod. I also had the A/F wired to a toggle switch, and the lighting of the boost/temp gauges hooked to another toggle switch.
Everything works great. The wiring looks very professional [at least the wires that you can see], almost factory. Cost me $180 to get everything done. I think it was worth it.
I'll try to get pictures this weekend when I head for the track. Can't wait to see what I run.
