The TPS isn’t required and most don’t even hook it up. 03-04 didn’t have it, 05-08 did. Sounds like your carb is from an earlier model.
The 49-state DRZ had the popular FCR39 carb, but the Cali model has the same BSR36 that you already have. The FCR is a favorite upgrade around here and there is tons of info on how to do it if you can find a used one.
It’s a 08 with tps the bike was not running When I bought. The owner bought a eBay carb without tps and it would start but it would rev so you had to turn it off. So I was looking to see if I had other options.
