A simple image editing program should suffice - I have made many
schematics in PSP 6, for instance. It's handy to make little
"boilerplate" images to copy from for frequently used symbols. If I
want a fancy symbol (alternator, starter, etc.) I usually scan an old
car manual and clean it up (enough cleanup that it's not copyright anymore).
Just using 8 colors you end up with a very small file size gif quite easily.
The various headlight relay diagrams on my site were made this way (link
1), as were the crossover schematics found here and there on my business
site (link 2).
I also made the wiring diagrams for my loader this way (link 3).
I might also suggest inkscape, it's open source and you can make them as
.svg files.

I've used a very old Visio for this, it's kind of cool in that when you
move things around, the connecting lines stay attached, usually, to the
objects. Although they sometimes snap to dumb locations.
The fusebox diagram on my web site was made this way, then converted to
gif (link 4), as well as the diagrams I put up next to the load centers
in my building.
