The setup is fairly simple. Two power wires, an extra door jam switch (How handy was that for MB to put TWO switch spots in the jam! ), custom low vacuum switch I had laying around (Forgot from where), and an extra one-way three-port vacuum valve. The hardest part is finding a good place to mount the pump, the SEL was pretty big with it's own low-vacuum switch but the SD is very small without built-in switch. I was going to mount it where the fuel tank lock was (The actuator had big leak that would drain the vacuum in 3 minutes) but I didn't feel like running power and switch wiring that far.
