I have a 00 prelude, and want to wire the autometer a/f gauge but not sure where to tap the violet wire (a/f signal) into, i'd rather tap into the ECU than the O2 sensors themselves b/c i wanna get the same signal on the gauge as the ecu is receiving but dont know where that wire is. someone on here must know..

Im not sure if youve installed it yet but since no one has answered you ill give it a shot. The wire coming off of your o2 sensor should run to the ecu, so I believe if you tap the correct wire on your o2 sensor you should get the same reading as the ecu. I have no clue where to find an ecu pin out for a prelude or I would check for ya, sorrry.
