Okay the Multi series needs to be programmed to since it is a blank module installers can program it to whatever vehicle they need. Unfortunaly to download the firmare you need a 40-60 usd cord, If there is a 12v shop around that installs them i recommend you take it there so they can flash it, usaully for free, if not you will have to return it and buy a single seris idatalink module, which remote start do you have? Yes it ties into the OBDII which means its databus integration you dont have to splice into door locks or any of that, it reads it all off of the purple wire (2nd pin) from the OBDII some casses you cannot tune your truck unless power to the Autostart is cut off, but that is easily done with a switch, If you need help with this i can provide pictures and more than enought websites for you to complete it
Edit: If you have no other options you could send the Idatalink to me and I can get it programmed for you and send it back

It's a man's obligation to stick his boneration in a women's separation; this sort of penetration will increase the population of the younger generation.
