so i have just came about this issue today, as my car would not start after i "fixed it" i turned the key and all power cut off when it was on run position. I checked voltage on main relay it was getting power from the ignition to relay, but now after jiggling a connector my radio started bugging out and turning on off on off on off with the key out =/ then i turn key on and the left turnsignal and now my gauge lights/indicators flash with the signal as well as my radio im really confused. NOTE:im thinking its a ground but i need specific locations as to were the fuse box grounds are? ALSO i just hardwired my reverselights/front parking lights because the previous owner FUC*ED it all up wired in wrong cavaties etc. but i shook a connector and radio went normal shook it again and the turnsignals went normal. Would love some input

 

The problem is obviously near the connector you shook, and is likely either a bad wire or loose connector.
