Hi to all members,

I was trying to determine what's the use of each relay in my 1989 K 100 LT box - both in a case one of them goes wrong, but also to buy a spare one and have them at hand, just in case.

The only one for which I still don't have a clue is blue one at the lower left corner. Having "Hella" inscription, it probably has something to do with lights - but what's it's purpose? And spare part no.?

Does someone has Bosch spare parts nos for all of these relays - it's often cheaper to buy them from Bosch directly, than through some BMW dealer.

Regards,

Thanks - but I thought the ABS modulators is the smaller one above in the picture, in the same group with the FI, LSR and Horn relays, next to temperature switch?

That is for the ABS warning lamp.
