So the other day my best friend and I spent 6 hours installing the viper 791 vx alarm system and remote starter into his tacoma. We also put in an alpine in dash dvd player, it was a crazy time! we basically had his whole car appart, I've never heard of anybody putting in a viper system DIY, it was worth the $250 we saved on installation, we mounted the whole thing under the carpet and what not so it's completely hidden, I'll post pics tonight.
