I am installing a ProStart remote starter and found that the vehicle previously had a remote starter, which was partially removed. What is left is a Universal Bypass Transponder, and a wiring mess. I need to know (or get a diagram) how to connect the transponder to the remote starter (I'm guessing through a relay). Can anyone draw this out for me or explain it well?

Any model number on the Universal Bypass? Most R/S companies make one. It might also help to know the Year Make & Model of the car. Here is a link for the Bulldog 791 Universal Bypass - https://www.bulldogsecurity.com/bdnew/newsite/pictures/instdiagrams/52.jpg

Usually they have +12 volts, ground and Ground When Running (GWR) coming into then and an antenna loop going out to the Ignition Switch for a key transponder. Check the box for a key inside.

Soldering is fun!
