Hello, Wesley -

You can purchase a repair manual, which you can download and save to your computer (and print out the pages you need) here:
https://www.tradebit.com/filedetail.php/280443770-ford-mustang-1998-1999-workshop-repair-service

Cost: $14.95

The download will probably be in PDF format, so you will need Adobe Reader software (free) installed on your computer.

If you wish a repair manual, which will include the wiring diagram you need, if you are in the USA, your local public library system probably subscribes to one or more automobile repair databases.

To access them (free) from home, you first will need a valid library borrower card. If you don't have that, you will need to visit your local public library during the hours it is open and apply for a card there. If you need to go to the library, while you are there you can ask a reference/information librarian about the auto repair manuals database/s. He / she can demonstrate how to access them and find what you need.

If you already have a up-to-date library borrower card, you can go to the public library system home page. You can log into your borrower account. After doing that you will probably see a link to Research from the home page. The library may subscribe to more than one auto repair manual: one provided by EBSCO and another, Chilton repair manuals. You will need to identify the right repair manual to access. If you need help in doing that, telephone your local public library and ask a reference/information librarian to talk you through the steps.

Don't know the web address of your local public library system or the telephone number to call? Conduct a search with your favorite search engine this way, using quotation marks as shown:
"Your city name, state" "public library" . Example: "Upper Sandusky, Ohio" "public library" One of the top search results will be the link to the public library home page.

Hope this is it closest I could find.
Good luck.
