As the title says, I'm interested in installing 2 or 3 gauges on my 05 ZX3 with 2.0 Duratec engine. I'm finding some deals in Craigslist such as an Autometer A/F and Oil Pressure Gauge for $45, but I'll bargain a little. My question is, where would I tap into oil pressure and A/F? I'm pretty sure I need a wideband MAF. Any help would be greatly appreciated.
