Secondary Vaccum Pump
Hey Guys is this what I need as a replacement? The pump took a dump on me...
The Bay link It looks like the correct item but it got me thinking where it stated "This pump is used in Kodiak/Topkick trucks for the AC & Heater Controls. On a 91-95 Corvette ZR1 it can be used as a direct replacement for the secondary pump. Can also be used on 1990 ZR-1 with this adapter (GM Part#12102747)" Thanks, Daniel

Re: Secondary Vaccum Pump
Yes they work and fit. You can also use Ford diesel vaccume pump, you will have to make up a jumper harness. I use the Ford pump it is available on e-bay for about $$55.

Re: Secondary Vaccum Pump
I need to get ta picture but somewhere down the line the pump was wired into the fog lights. Any thought as to why someone would do this?

Re: Secondary Vaccum Pump
Does the ECM provide +12V, or a switched ground, to turn on the pump? GM often uses switched ground to actuate devices controlled by the ECM or CCM, so perhaps the +12V source is shared by the fogs and the pump?
