one wire differential pressure switch

[dtcohen]

Hi,

What can be done to keep my brake warning light functioning when I swap to a combination valve with one wire? Can I take the two pin switch out of my old differential pressure valve and put it in the new combination valve?

Thanks
Daniel

I don't believe I've seen one work in more than 40 years.
Most get unplugged or the bulb burns out.

dtcohen,
Been a while since you posted this question. You solve it? How?
I'm rewiring my 1970 Highboy and trying to figure out the best way to proceed.
Hope all is well. Thanks.
