Hello all,
My latest project with the blazer has been to reassemble the bank of vacuum solenoids and their associated wiring pigtails to get rid of ses light.
When I removed my vacuum pump a while back I just cut the Oem pigtails off and pulled the bracket, solenoids, and pigtails all in one. Then I lost it.
Beer may have been involved.
So now I've got new pigtails and solenoids, but I have no idea which wires go where.

So I'm putting out a request to the forum for someone with a 94 or 95 "s" vin truck to take a nice clear pic of their stock vac solenoid wiring setup ( colors n stuff)

Thanks, yall are great.

I could be mistaken but I suspect that schematic depicting the vacuum pump connecting to the aft WGS port is incorrect. The vacuum pump should always be connected to the most forward ports while supporting devices connect to the rear ports.. Just as shown in the picture

It's a waste of time if you are vac delete. The PCM uses that baro sensor to read the vac signal commanded by the solenoid. Still going to toss the code.
