just trying to make sure. Will a civic or integra main relay for fuel pump work for a 4th gen lude? Also o2 sensor's? Or do i have to get all these parts off a prelude? Searched a lil bit. nuthin much came up.

 

anyone?

 

I'm pretty sure the relays are interchangeable because most of the time a relay is a relay, as for the O2 sensor, I'm not sure if the newer civics/tegs are interchangeable but im almost positive 92-95 civic O2s are not interchangeable, what year prelude do you have?

 

I have a 92 prelude. My o2 crapped out and i was wondering if i could use one form a gsr? My friend has a spare laying around so i thoguht i might ask. thanks for the help.

 

The O2 sensor should be the same.
It will have 4 wires. 2 white, 1 Black, and 1 Grey

Not so sure about the main relay though. Its a module that contains 2 SPST Relays, a few diodes and a resistor. This module has the simple task of supplying ignition power to the ECU and Injectors, plus it houses the fuel pump relay. I would not be surprised if they are all the same anyway. If it has the same number of pins and footprint then chances are, you will be ok to use it.
