ok so I need to install my a/f and oil presure gauges but idk where to run the wiring to? I looked for places on the firewall and not finding anything would be helpful… also if I do a narrow band a/f then which wire on te ecu do I need the car is a 92 integra gs if that makes a difference… and I know narrow bands are useless but I still wanna install them till I can afford a wideband… thanks
Maybe this will help, when I ran my power line for my amp, I ran it through a grommet by the AC evaporator. There is a drain hole with a tube sticking out, it had enough room to run my power line (12ga) for my amp. Maybe its large enough to run your wires. If not, you can always drill, and put your own grommet in.
