DeathScythe Posted December 18, 2008 Report Share Posted December 18, 2008 How did you disconnect the main wiring harness that goes into the firewall on a 93 Lumina 3.1. It is the one on the passenger side next to the strut tower. Thanks AJ. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted December 18, 2008 Report Share Posted December 18, 2008 T30 torx from under the hood. I use a longer extension (8") push it is, tap it a few times to make sure it seats... then turn. Quote Link to comment Share on other sites More sharing options...
