I recently purchased a piggyback for a 2002 auto lancer and I wanted to know which version it was. I was told that there is a number located on the front of the piggyback and that the number can determine the version. The number on my piggyback is PSC1.

 

I did but he didnt know because he was the second owner. The image is the only one I have right now because I havent received the item yet. However, if you look at the wire colors you might be able to determine the version. IDK

 

i believe its a v1 since it has a vacuum line coming from it the v2 i know dont have it

 

Yea but I thought version 1 didn't have the violet wire. Only version 2 has it
