Hi Troy and welcome to FBN! Are you here in Washington State? I have a great factory book wiring diagram you can use but you're about 100 miles North of me. Have you tried the wiring diagrams in the Haynes Manual yet? There is a 'good' representation in the back of the book. You can pick one up for about 20-25 dollars at a Auto Zone or Schucks Auto Parts Store. However; if you looking for the real deal in a four page layout, then you are more than welcome to copy mine. Let me know. :f_bananarockm:

Thanks Larry! I have a great wiring diagram to use but I have no clue how to use a scanner. I was just going to let him borrow my book. :12EMOTICHEERS:

Hey Guys,
I'm new to Firebird Nation but am supper excited to be involved. I have loved classic cars my whole life and have finally just purchased my first! I have a 79 with a rebuilt 350 motor Edelbrock 1407 Carb. It runs good for the most part but some of the wiring in it seems like it was just thrown together. I don't want to purchase a whole new harness so basically I'm looking at replacing the wires that are bad and I'm not sure what gage is is appropriate. Any help would be great.
Thanks

Hi Michael and welcome to FBN. The thread you have posted under was originally posted in 09. You may be more successful in getting help if you start a new thread. However www.78ta.com has the entire service manual on CD for about $30.
