Hello all, I've got my girlfriends car apart, and can't find the relay. Found three other similar sized relays behind the glove box, but not for fuel pump....saw none on the firewall inside engine,compartment..could someone please tell me where to find it?

 

do an online search "560sl fuel pump relay location" there are pictures. it's behind the glove box behind idle control module.

 

Thanks, I found it and changed it my confusion was from it being labeled as a knockdown relay? Had a 6000rpm printed on it, and the replacement had an extra pin. But it works....
Another question... S it possible to put the idle relay in backwards? Seems to be idling higher....about 1200 rpm....
