ClassySoob Posted July 6, 2018 Share Posted July 6, 2018 For the ej swap, do I need the ej harness for the alternator, or can I just wiring it using the existing wires from the EA. Link to comment Share on other sites More sharing options...
el_freddo Posted July 7, 2018 Share Posted July 7, 2018 You'll need the wiring from the alternator to the main loom. Then splice this into the existing EA loom. relatively simple to do. Just make sure you solder and insulate your joints really well Cheers Bennie Link to comment Share on other sites More sharing options...
silverhelme Posted July 7, 2018 Share Posted July 7, 2018 I did mine using the existing alternator and wiring and have had no problems with it. I did have to shorten the main output stud about a 1/4 inch for clearance. Link to comment Share on other sites More sharing options...
DaveT Posted July 7, 2018 Share Posted July 7, 2018 Just for the information, the risk in using the old existing wire is that it is not sized for the higher output of the modern alternator. The stock fusible link should cover most failure modes ok, but not allow the full use of the higher output. Link to comment Share on other sites More sharing options...
