HAYNES REPAIR MANUAL
See if your public library has a Chilton's book for your Cadillac.
You can find the fuse box diagram for a 1989 Cadillac Brougham in the owner's manual, which typically includes detailed diagrams and descriptions of the fuse layout. Additionally, you may find helpful resources online, such as automotive forums, websites dedicated to classic cars, or repair manuals available for download. Checking platforms like eBay or Amazon for service manuals specific to the 1989 Cadillac Brougham can also be beneficial.
You can find the PCV valve for your 1987 Nissan on top of the engine. The PCV valve will be near the air filter housing.

your local librarie should have a mechanics manuual that you can photo copy ! Good Luck !
The fuel pump is mounted on the side of the engine block near the front. Follow the fuel line from the carburetor and you will find it.
Up your but and around the corner!
It should be in your Owner's Manual. I think it is on page 99 or 100. If you do not have the manual, you will need to either find an image of one online, purchase one online or find someone who has one that they can show to you, either online or offline. If you are still stuck with this, try the Cadillac Owner's Forum, there are many forum members there who own such cars (like me) that would be more than happy to host photos of the diagram for you.
