I've already searched and found nothing helpful. Anyway I've got an eletrical oil pressure gauge and electrical A/F ratio gauge(both autometer) and cant find easier to understand instructions then those that come in the box. Is there a link that someone can post, a website I could visit, or can someone walk me through this? I'm hoping to install them on saturday, but I'm a huge noob when it comes to electrical stuff(actually I'm scared of all the wires, I could screw something up) Thank You in advance for all the help. Oh and if it matters the car is 00 Civic Si.

 

I think you need a mechanical oil pressure gauge. Then T that off the back of the block. As far as the AF gauge find the sensor wire that comes off of your primary o2 sensor. Not the ground or the power but the one that sends the o2 voltage.

 

Oil gauge:

There should be a wire to splice into the stock oil pressure sending unit which is located right next to the oil filter, it's the only sensor near the filter so there's no trouble finding it. Red wire goes to battery positive, black wire goes to ground, and the remaining white wire splices into either your parking lights or gauge cluster.
