WTH 2-wire firewall mounted vacuum modulator
Anyone know what this vacuum doo-dad is or how it's supposed to be plumbed? 1968 C3
Appears factory.
Two nipples,,no hoses currently, 2 wires, PO apparently re-wired using aftermarket white wire / blue connector on bottom. Solid wire, I might point out, not even stranded. Yeah, I know, OMG...
Photo is looking down from just in front of windshield.
Vehicle is small block, 4 speed, AC car. Any/all Vacuum diagrams or URLs thereof would be most appreciated.
thanks in advance
