I have a question

I have a dead short that blows fu2 which is the fuse for the instrument panel lights, I have the wiring manual and have found the correct circuit but I am not sure what one of the terminology means one side goes to a splice 806 the other side goes to splice 805 if I remember correctly, my question is in the description it says near T/O what does T/O mean? I'm thinking the T might mean terminal but what about the O?

Thanks in advance for your help.

I reloaded the wiring manual so now all pages are complete and here is the link to it: http://www.supermotors.net/registry/24302/83503

Reloaded link from updated thread, so now you don't have to search for the new link.

I would have said Turn Out, but Take Out works too. It's where the wiring harness branches off to something, such as the T/O to the ignition switch, or the T/O to the headlight switch.

Vectored wiring diagrams

I got a bug in me to try and make vectored versions of the 79 master wiring diagrams. The only diagrams I could find on the internet were raster images from scans, which are fairly low res and lots of jpg artifacting.

Vectored versions are super clean at any zoom level and print as sharp as your printer is capable of. You could print a wall sized one and still have razor sharp edges and text.

My first goal is to just make direct conversions with only some very minor formatting changes. After that, I may try to make some enhancements. For example, colorizing them so lines are colored same as the wires. Maybe add some extra info, remove some redundant info, eliminate abbreviations, etc.

I just finished page 1 of 9. It took many hours, hoping I'm more efficient now for rest of pages, but will take a long time to get through the rest. I also made the circuit code page scans into a spreadsheet which makes them sortable, searchable, filterable, etc.

Attached is 1 of 9 if anyone is interested or could find this useful. I would also be interested if anyone can do some review for mistakes, or any feedback/suggestions.

Hmm, looks like pdf/zip files are limited to only 10k??? That's a weird limit for PDF. File is only 75k. So for now, I have the files hosted and linked to below. They'll be available as long as I maintain my account. :)

that's a lot of effort but I'm sure many will find useful over time.
thanks for all the hard work.

are you re-drawing them in CAD from scratch? That looks fantastic.

totally awesome dude

that will come in handy for sure

I have some 3'x4' diagrams I blew up for my 62 Cadillac
you need a magnifying glass in the factory service manual to see them
but on the table sure makes things easier to read and repair

thanks again for all your effort

Thanks! Yeah, I put the scan as a background layer, and then draw lines, shapes and text over the scanned image.

I'm using OpenOffice Draw since its free and does what I need.

For the circuit codes, I used an online OCR scanner and then spent a couple hours pasting things into Excel and fixing the many mistakes the scanner made.

This is one of the main reasons I'm making these, so I can print them, or sections of them, in large format for easy reading.

im sure there are a whole mess of people that will appreciate all the effort you are putting in on this project. I have been using CAD for years to do small things, and a few big things. Im by no means an expert, or even a novice, but I know exactly how much work it is to take on a project like this. Looking at your initial drawing, you have done a fantastic job. Im just thankfull I have all the drawings for my 94 in vector format.

About halfway through page 2. Very slow process, but get an hour or two in here and there. Tried a few more auto tracing/conversion apps, but what they leave you with is more work to correct than just doing it from scratch.

Just wondering if these are still in the works. I've got some electrical gremlins that need squashing and this would fit the bill nicely!
