I just put a new stereo in my 2002 Ranger Edge, after a few mishaps with wires i got it all installed. During the mishaps i combined 2 power lines I thought were just Positive...but when turned key to just acc...the truck started......now after getting all wires fully place when i try to start truck it just clicks and my Theft light blinks real fast.....

How do I test or check for correct fix....already checked and tested starter, searched for supposed secondary Solenoid (didn't find one) , and checked all relay fuses and mini fuses.......I am thinking PATS or ignition but before I spend that amount of money would love to verify first.
