Can I use a 1991 civic main relay to replace my prelude relay? They look identical, I have run the tests on my relay and the coil will not operate for the fuel pump. It appears that the relay is a rz-0088 for the civic and the prelude is rz-0081, anyone know? The civic is half the price of the prelude, plus I can't seem to find a prelude relay available. Thanks in advance

 

Im sure as with fuses as long as its the same amps/volts/ohms rating and fits there should be no problem.

If you use the wrong size you can melt wires.

 

Many of the relays look very similar, but the plugs or internals are different. I would say look at some junkyards or on ebay to find a correct one.
