Many local libraries have free access to alldata which is a popular information source for many independent shops. Otherwise you could always pick up a chiltons manual.

As said most libraries have repair information.
Some dealers or repair shops may print you off a copy of wiring you need.
AZ online has a little All Data.

But for the your very own stuff and 10 minutes online with a plastic card good for 26.95 US $ You can be set to go with a on line one year sub. for one car all data repair info sub.

Its not a bad deal if you use it!! The librarie might charge you $.15 or so for every printout. The online deal will give you a ton of information and it only costs you the subscription for the year and as many ink cartridges as you can go through to print off whatever you need. Not to mention the easy access any time from just about anywhere!!
