I've been going through the available info for installing a jc4
vacuum pump for the brakes, but still don't have it quite figured out.

The brake booster we've got has two taps (inlets?) instead of just one.
Should I just plumb the jc4 to the extra tap and leave the
other side of the pump open? All the instructions are for a single
inlet booster.

I see how we can use the yellow wire for the accessory input, but
where should I get the 12-volt power? Is this a 10-gauge wire run directly
to the battery, or can/should it be from somewhere else?

The horror stories make me really want one of these!

thanks,
Karen
