2009 WRX aftermarket gauge wiring
I have a 2009 wrx and i am doing tons of visual things to the car right now. i have the whole dash torn out, and i just bought 3 gauges. boost, exhaust temp, and oil pressure. i have the boost sensor in, and i tapped my manifold for the bung for the exhaust temp, but could anyone tell me where the best place in the block is to put the oil pressure sending unit? its a smaller thread, i cant think of the size off the top of my head. and another thing, i have the illumination source and the ground for my wiring harness for the gauges, could someone tell me the best place for the constant power, and switched ignition sources to tap into? I would really appreciate all help! thanks.
