pillar guage wiring... firewall wiring 98 prelude sh
how would i go about wiring 2 pillar gauges in a 98 prelude sh?
where can i easily go through the firewall to wire to the distributor for a tach?
where does the a/f guage wire tap into on the ecu?
i am wiring air/fuel gauge and pillar sized tachometer in this car.
where should i tap for power for each gauge and where is the best grounding point?
thank you

Use a volt/ohm meter to find a good ground and power supplies.
It's not that hard to find a grommet to go through or drill yourself a hole and put in a grommet.

i was just wondering if anyone knew specific spot on the firewall where the grommet was, i am used to working on integras and i know this would be different im just trying to get ahead here so i have an idea of what im getting into before i start...
i was thinking of getting power from a fuse that has power when the ignition is on, like a radio fuse or something.. and i was thinking of just grounding both to the same bolt somewhere around the fuse box..

into the o2 sensor? okay i thought it was tapped into the ecu.. that is how my dad did my a/f gauge in my integra.. but the o2 could be a better choice.. how would i tap into the o2 sensor for the gauge without ruining it?

i have these three wires left..
tachometer- 12v yellow
accessory green to dist.
air/fuel- accessory purple to o2 sensor
whats the best way to get them through the firewall i.e. what side of the firewall should i drill? where?
and how do i tap it into the distributor and how do i tap it into the o2 sensor?
which fuse should i tap for power? i have it on the starter signal 7.5amp now.. but that doesnt seem correct?? please helpp!!!
