A general purpose rectifier diode will do. 1N4004 for example.

The diodes prevent the relays from making all sorts of strange buzzing & chattering noises when you switch off the ignition.

I wrote that guide, so if you need any help, just e-mail me. Lots of E30s are running my solution, so i'm pretty clued up with common problems.
