Hello fellow G body family... I need any kind of help regarding my firewall engine connection. I have a 1979 Malibu and I’m doing an LS3 swap... everything is nearly done but I ran into a problem... it seems that my firewall stock engine connection does not match my inner (under the dash) firewall connection..,, this has put my build in dead stop until I figure out what connection i really do have... I believe the inner side of the firewall connection is from a different year g body.... can any one please provide me with useful help or does any one recognize this year connection ... I’ve posted two pictures of the firewall connection... I appreciate the help. The connections don’t mate up with each other .. I believe they’re two different years .
