relays and part numbers needed please!

[E30mann]

Hi all, new to the forum, am restoring an E30 I got from an auction, and am getting the electrics and fuses sorted first - trouble is, some idiot swiped two relays from the fusebox! have checked the guide on here and see that I'm missing relays K2 and K5 - horn and seat heaters. anybody have any idea what the part numbers should be for these? have checked on ebay but any sellers with 'em for sale don't seem to know, so any help at this stage would be very much appreciated!

Ordinary bog standard 4 pin relays, nothing special about them. Note, some of the relay and fuse positions are normally empty, although the two you mention are usually present.
K5 is also for electric windows and roof.
