i went to turn my 1988 t2 with s5 jdm swap and i turned key to off position and it stayed idling then sputtered out... the next day i did it again and it turned off right away but then next time i tried it, it sputtered out again... the real problem is it stays on after i turn key off and then sputters out... im guessing a short in one of the wires in back of the round ignition turn...

 

Alternator is back feeding into the ignition circuit due to ?????????????? Messed up harness configuration.

 

well i did take out some of my harness... the piece of harness that goes to speakers and ac/defroster and it goes to some other interior things... would this be the problem?
