Do you need a wiring diagram or just labels of what fuses go where?
I found a 79 diagram, it has the blade fuses.

Some one will have it

Found this on Willcoxs site for 78

You can get a reprint of the 78 owner's manual online for about $10.00. Page 6-5 has the fuse box diagram and descriptions.

Here is a link to the GM Heritage site. On page 92 of this pdf file is a listing of the fuses and their location, but no diagram.

But, don't 78's use blade type fuses? I know my 79 does and I assumed 78's were the same.

My March 78 (Pace Car) uses glass fuses. I wish it used blade.
