Since the relay didn't seem to hold up in your application, I wouldn't use it as a replacement unless you can somehow water-proof it.
As per
2011 Nismo#91, the coil needs to be 12 VDC and the contacts rated for 30 A (when two figures are given, the first is usually the "make" rating and the second is the "break" rating - when in doubt, go with the higher figure).
If there is no connection to 87a, you can use a NO SPST (Normally Open, Single-Pole Single-Throw).
