I recently installed a viper 3305v alarm system in my 91 c1500 and cannot find any sort of lock relay, also iv tried splicing into the black- red / black-white wire (it changes from one end of the plug to another), and iv tried the light blue wire that keeps being referenced in diagrams and cant get it to work. I'v been at this for the last three days and so far am not getting any were any suggestions???
