Restoring my project at the minute and the time has come to sort out the brakes.

Looking at the Tandem setup as i have a 5 way proportioning valve and was told it would be the best way to go some time ago.

One question i have is to do with the plumbing of the valve, Im not sure where the 5th valve to the top of the unit is supposed to go?

Apologies if this a silly question, but its one worth asking.

Thanks in advance for your help.

Cheers
Nick

I thought that was was where the brake light switch goes on some cars?

2 inlet ports point up
3 outlet ports face down , single one rear brakes , two side by side to front brake hose's
