Can you swap relays?

[caffeinatedsoap]

Can you swap relays from an e36 into an e30. My car is dead and I think it is a relay as it won't crank at all and the battery is good.

I have an e36 m3 that runs well I was wondering if I can yank relays out of it to test in the e30?

if your still looking for an answer to this, yes all bosch relays are the same just make sure it has the 87a post if it needs it, i dont think the e36 uses an iso relay but it wouldnt fit anyway so you should be fine.
