I have a 94 sc300 with a 1jzgte swap , the alternator is bad. Ive never changed one and ive seen the round and oval plugs advertised for sale. Not sure how to determine which plug i have or what cars have an interchangable alternator that i could buy. Pics and input would help. Thanks everyone.

 

The alternator is held by a 14mm bolt and a 14mm nut take it off and pull the plug to see which one youll need

 

Thank you. After pulling it i see that its oval.
