Fibbles diagram is spot on. 02GF what the hecks that.

This, as per description, works by shorting out the lamp i.e. lamp is off when the fluid is high as the switch will be closed.
When level goes low, the switch is open circuit and lamp will be on.
The resistor is there to prevent the 12 V shorting to 0 V and since it will be in series with the bulb, to make the bulb a bit brighter, a lower
voltage i.e. 6 V bulb is used.
Both circuits, including fibbles' one, will draw current all the time - not ideal - you need to have circuit power from igntion switchto avoid
battery draining.
If a LED lamp is used, the current drawn can be reduced.

Well i wired it the way fibble said and it works fine except the relay doesnt change back and switch the light off when i the circuit is complete
again (reservoir full)
How long can i resist the temptation to drop a V8 in?

Are you sure that your reservoir cap is working correctly?
As said previously - most caps I've seen make the connection when the level gets too low. Generally this makes the wiring so much simpler, a
trick that most car manufacturers wouldn't have missed.

Speedy you really need to meter out your cap/switch. Something as simple as this circuit should only take at the most an hour to sort out. If
you're struggling here then you're gonna be lost when it comes to the column switches etc.
I don't mean to be nasty or anything but if the last lot went up in smoke then perhaps you don't fully understand circuits enough. You may
need to/should get someone else in to do it. The last thing any of us want is a post from you showing a burnt out shell after all your hard work.
Sorry if that offends you but we all have limits.

If it looks wrong it probably is wrong.

Yeah i know what you mean. I dont need to worry about the column switches. Iv done them already 
This is the last thing left. Iv had a good look at it but it seems to be working correctly. I too would have thought it would make more sense to make
it the other way but the only thing i can think of is if the wires connected to one of the ECU's on the donor car (it had a few!).
It does seem stupid how something this small could be so hard to figure out.
Does anyone know what size the reserviour cap is on a sierra MC? If that fits i think it would be soooooooo much easier to just fit one of them

Probably not such a daft idea - most brake systems were made by only 4 or 5 different manufacturers, so I wouldn't be at all surprised if the
caps from some other cars would fit.
Maybe a visit to a scrappie would be in order - take your Jag cap and see which reservoir it fits. The only thing to watch would be the level at
which the cap makes the connection - you'd want it to be somewhere round the 'Min' level of your reservoir, or just under.

take sa look at asn Easibleed kit and you will see that the above is true i.e. not that many variation in caps.
I can measure the sierra one tomorrow if noone else gets round to it.

I have an eezibleed system in the garage so i will look on friday.

reservoir neck diameter = 45 mm
too difficult to measure thread pitch since there are about 1 - 2 threads on the neck.
Ford 74470340 is moulded on the switch assembly.
now my fingers smell of brake fluid

Thanks for that (sorry about your fingers). Im pretty sure that is the same size as mine
