OK Kiki, you got me. I went to my assembly manual (better known as AIM) and did not see what you are talking about. It has been 2 years since I have had mine apart and I just do not recall.
I would go to another forum like the Corvette forum and ask the same question. They have more activity on that site and it is very possible that someone has done what you doing very recently. Sorry I was not more helpful and good luck.
What year is this out of????
My 81 is a vacuum operated system... I think most of the generation are.mine has a selonoid on the rt side of the engine, but the engine needs to be running to create the vacuum.
