I've added the switches to the above diagram, hope it helps you -

where's the switch for the fogs?  I see them linked to the driving lights switch.  I'm confused.

And you power the relays, and then go to the switch?

Todd,

I do run the driving lamps only with the high beams and the fog lamps only with the low beams.  I can see that I wrote my description incorrectly - this image is how I did the power wires to the relays. 

Like yours, if I have the driving lamps on, I can use the dip-switch and jump back down to only low-beam headlights - unless the foglamp switch is 'on'.

jeg, beautiful job with the lengths, heatshrink and colored tags.  This inspires me to rip mine out and do it right as well.  I don't know how your back made it through that.

Unlike yours I run the driving lights on with the highbeams.  This lets me just use the dip switch for oncoming traffic instead of fumbling for the driving light switch as well.

Get a tool for pulling nylon ties tight, and then cutting them off flush.  This will prevent them from cutting your hands as you work around the new wiring.

The solid cable for the heater shut off valve? Bend the end down and towards the flat metal of the lever  so that it does not cut your fingers to shreds.

Nice work.

After several iterations, my relay installation project is pretty much finished.  The mini now has a full compliment of 8 relays (high beams, low beams, fog lamps, driving lamps, horn, A/F meter, 2 x aux fuse panel).

I found some really neat relay sockets which have 3 additional sockets for blade fuses; thus eliminating my need for in-line fuses to the lighting and aux. fuse box relays.  These 2 particular relays are fitted with 2x30A fuses from B+ to the relays (30) and a single 3A fuse from the switch.  With this configuration, the 'relayed' switched accessory aux. fuse box has a 60A max capacity and currently serves the fuel pump, electric fan and illuminated cigar lighter.  The remaining 3 fuses on these relay sockets are 10A radio, 25A high-beam headlamp & fog lamp relays and the 20A is for the low-beam and driving lamp relays.  It sounds 'criss-crossed', but I did this intentionally as the highbeams will never be used together with the fog lamps and vice-versa, so there will never be any overload on those 4 circuits.

One of the biggest hurdles was that I needed to install a smaller 1-liter windscreen washer bottle instead of the 1.7-liter bottle that I previously enjoyed.
