Quick intro, I was an installer for many years in my previous life. Worked for Best Buy, Circuit City, Audio King, and Ultimate along with a few local shops doing custom work. I live in the freezing cold state of MN and have done hundreds, if not thousands, of remote starts. I remember the days we would be booked out 2 months installing them. Ok, on to the help. I am putting a Viper remote start in my 2015 Subaru Legacy and am looking for a Directechs doc or similar which has the information for the rear defrost. I looked at Ready Remote's site but it didn't have that info and I am not sure if I trust it anyways. Just hoping someone can make my life a little easier and post the complete Directechs doc. Thank you. Replies: Posted By: tonanzith Date Posted: November 13, 2014 at 2:53 PM 2015 Subaru Legacy DirectWire Vehicle Information

Posted By: shadowinfector Date Posted: December 02, 2014 at 8:33 PM hey are you using an idatalink module? and if you are where did you tap in for the IMMO DATA wire , i went behind the fuse box where the white connector was, but when i searched for pin 45 on the connector there was no wire there......wth.....can you help? thanks
Posted By: shadowinfector Date Posted: December 03, 2014 at 10:13 AM so i just finished the install, i went straight to the ecu on the passenger side, lower plug, pin 38 Data Bus - WHITE/ blue , on pzev vehicles there is NO wire at the plug on the tech sheet from idatalink. You need to go straight to the ecu on pass side engine compartment.
