Can i change the 2 blue relays on the picture (traced with red) with the orange ones like others, i'm asking couse i we seen on some others e30's that they are all orange. my car is a pre-fl 87.
Yes, if they have the same no of pins. Relays appear to be K1 (low speed electric fan relay) and K7 (unloader relay). Both bog standard relays.
K1 and K6 are only fitted to aircon cars, so I presume yours is.
