Has anyone here installed on before? The one I got came with a Wiring schematic but beyond that there’s no more installation instructions. 

Which make and model is the kit and can you post the wire diagram? 

What year and model is your truck?  Your signature is not filled out. 

Has it ever had a remote or power locks before like the high line model?

My truck is a 98 ext cab, auto, SLT trim so it has power locks and I think at one time had a FOB but I don’t have it. The remote start is ProStart brand. I can take a pic of the schematic with my phone but I’m not sure how to upload it to this post from my phone. 

I did one on my 97 gasser. Search online and you can find limited info. The12volt.com has good relay schematics for door locks. Get a factory wiring diagram and triple check everything before cutting or splicing. 

I installed a Viper SmartStart in mine. Tied it into the power locks. One remote that both remote starts, and locks/unlocks the doors. 
 

Second on the12volt.com. Great resource. 
 

Since you do have the wiring schematic, not sure what you’re asking for? Is there a particular question you have? I’ll be happy to help.
