Anyone happen to have a fuse box diagram for a '78 Chevy? The wiring on my van is a shit show (with multiple wires coming from the box spliced & taped together) and I'd like to be able to make some sense of it.

Nobody? Even if it's hand drawn on a Krispy Kreme napkin, I'll take it.

I already have a Chilton's manual and despite all the wiring diagrams in it, there's no mention of the fuse box.

Chilton's manual is a gen info book....If ya ask me there crap.

Get a factory service manual you wont be disappointed ... ya ya they cost more than the comic book you already got... Its worth it !

Buy it right or but it twice ...

Yeah, The Chilton's manual is pretty bunk. Mine came with my van, so it's no big deal to buy a good one.

$30 on eBay isn't that much more than buying a Haynes or a Chiltons. A factory service manual really is the best tool you will ever buy to work on your vehicle.

But you have to be careful , my yr van has 3 books to completely cover my van.

A mechanical, emissions and a electrical book ... each refers to each other in fixin things.

Ask Wedgy he's gotten all 3 for me as Christmas presents over the yrs.
