I am using a twin master cylinder bias bar setup & was looking for a remote reservoir, a friend has just given me 2 of these brand new rally design remote reservoir kits: http://www.rallydesign.co.uk/product_info.php?products_id=16867

I know that I need sensors in the caps so my question is, is it IVA ok to use 2 separate reservoirs & if so, do I just buy 2 caps with sensors built in ?

Also, how would I wire them up to keep the IVA man happy ?

Cheers - Andy

You'd wire the switches in parallel so that if either closed, the warning light would be triggered.
But seems like a faff, who not sell and get a single reservoir with 2 outlets for simplicity

Wire one terminal live to your warning light, the second terminal to one side of your first float switch, loop to the second float switch and then loop to handbrake switch.

Then earth the second terminal on all your switches.

Or use one of these link
