RPO codes
Hi, I can't find 2 of the 74 codes for my car. They are E7Z and YS1. I have E5Z-speedo adaptor delete and E9Z-speedo key delete. I assume the E7Z is something with the speedo too ? The YS1 comes right after the YR1, which is custom front seat. I found a YS2 for a deluxe rear seat, but not the YS1. Any enlightenment on these 2 codes is appreciated.
