TPMS mixup
 

when I mounted the new wheels - (Venaci's) I left out the TPMS due to the 90deg valve stem location right in the middle of the wheel. When they took out the TPMS out of the OEM wheels, they mixed them all up before I could label their original location so I could install them for later when I found a good solution.

Well, I found a cool adapter that will solve my problem and allow me to use my TPMS on these new aftermarket wheels. (DIY: Mount your tire pressure sensors (TPMS) to aftermarket wheels(Volk, Work, etc) - G35Driver)

My question is how do I remount these things without knowing their original locations. Just install them and take to dealer to reprogram?

Doesn't matter, the Z doesn't tell you which wheel is flat anyway.

but if they arent in the correct corresponding tire, the tpms light will stay on

This TPMS thing is such a hassle. There's got to be a way they could have made this easier. As far as I can tell there are only 24 combinations so if you start now you might finish by the end of the day.
