Look on the firewall, driver's side. You'll see a box with a wiring harness attached with a 10mm bolt. It'll be on the box. If the external sticker has come off, remove the box (disconnect battery first) and you'll see it on the box where it was sticking in the cab. It'll be the largest size font characters on the sticker.
