Re: Idea for replacement EGR solenoid
I think they still worked with wiring hooked up backwards. I have no idea if there were any further ramifications like life expectancy or not though. That is how I found the positive sign on them too. More than likely it's on there....but I suppose all mine were Delco parts..

Re: Idea for replacement EGR solenoid
Hello Ward!!
The LT1 EGR solenoid will work ,and so will one off of a 2.0 L Cavalier/Sunfire. The EGR solenoid is just a fancy electric ported vacum switch. However, the solenoid clicks on and off a whole bunch of times every minute, which is known as it's duty cycle. As it clicks on and off it applies vacuum, and then releases the vacuum, as required to get the EGR valve to open, and close as EGR is either required or not required. Any EGR solenoid can be made to work, you just have to wire/vacuum hose connect it properly. As for mounting it, it's up to you how you do it, you can even mount it on the firewall.
Also, the 9v battery is a good way to test the solenoid, especially when you find one in the junk yard, test it first before you take it off the donor car, saves time!!!

Look up EVS9 at AutoZone or ACDELCO 214329 (14102002) GM Original Equipment.
You may need a different connector for an older (pre-1988) TPI.

Re: Idea for replacement EGR solenoid
You can make a pigtail extension and use a vette egr solenoid.
It mounts on the rear thermostat bolt.

These should work
