I'm planning to make my MGF's EPAS switchable as per Rob Bell and Will Munns excellent article. Switch is on it's way but I'm having an issue sourcing an automotive 6 pin DPDT relay in New Zealand. Automotive rather than standard electronics one which will need soldering.
Does anyone know if 6 pin automotive relays actually exist and if not, can I piggy back two standard 4 pin relays and divide the coil switching supplies?

Just got two micro relays that I'll zip tie together and bridge the coil sides together. Issue now is the blown bulbs in the recirculate switch. These must be the worlds smallest bulbs and the switch has two of them in circular yellow carriers.
Rated 1.2W I'm not even sure whether they are LED or not.
Does anyone know where I can get replacements or advise a workaround?

If the original bulb is rated 1.2W it will definitely be incandescent. An LED that put out that small amount of light would only demand milliwatts. Once you have identified the type of bulb there may be an LED replacement available

That is a "grain of wheat" bulb which can be found in electric stores, removed from yellow bulb holder and green rubber cap replaced to new bulb.

I could have sworn wheat was a seed not a bulb, you live and learn.

Wheat is a grain not a seed. Well it was when I was a boy brought up in the countryside.

Google seems to imply a score draw I'll settle for that

Wheat is a grain, which belongs to the grass family. A grain is defined as a plant that produces a dry edible seed, which is called a kernel or berry. Wheat produces a seed that is commonly called a kernel.

Thanks Roverlike. I've found some possible suppliers so I'll order some. Knowing they're available, I'll now wire up the switches for EPAS override and the DRL

I had a bit of time today so i've had a go at a guide for you lot... Its nothing amazing but as a 'guide' it will point you the right way.

I was gonna write it up in the how do i... section but i don't have rights to create new threads so instead its here as a PDF file to download.

Get it here: http://www.violentangel.net/stuff/car/How to Rover 25 Switch LED.pdf

Let me know what you think?? Worth writing??

Having trouble getting small enough grain of wheat bulbs to fit. They must be 3mm X only 4 or 5mm. 7mm's don't fit and they have multistrand copper which don't hold shape in the holder. Now thinking of converting to LED, I've found this very old thread and dead link from @dynamis_dk. Has anyone got a download of his guide or advice please?
