Relays and such....

[blues3]

Just going through the re-ending of my loom and a couple of labels have dropped off certain bits of kit. The circuit diagram is as about as much use as a useless thing so if anyone knows what the red and yellow relays cover off it would help big time.
Also there's a small black box (Aluminium, say 3inch by 2, with heat fins on the top. A bit of Lucas kit if memory serves) What's this for?
Thanks guys.
Lord knows what I'd do without this site and the interweb. Label stuff up properly maybe.

Dim dip module, you can just unplug it and loose the dim dip.
