Viper alarm/remote start help please

[99yota4]

I want to get a viper car alarm/keyless/remote start system in my 1999 t4r. Getting it at bestbuy is really expensive and want to buy the unit somewhere else. What bypass module do I need for my truck? Thank you!

Also if anyone is selling their viper system I'm interested!

I Used a PKALL with my Viper 5901, bought the alarm on Amazon for $200...
