it from the R12 to the R134A and I had to get a new high

Have you found an answer yet? We are having the same issue and aren't having any luck. Thank you.
I cannot BELIEVE no one on this earth can answer this question????? Where does the SECOND wire need to connect? Ground? Any old ground??? How can NO ONE KNOW THIS? I have been searching for HOURS online!!!
1 wire goes to 12 volt wire from the original plug and the other one needs to be grounded, it doesn't matter which wire goes where. Just did this on my 89 silverado and it works fine.
