Someone posted info that some of the locations for relays/maybe schematics in the owners/haynes manuals is wrong.

Anyone have info with what is really in the car and where it is located and if there are any schematics that are more accurate?

Need the factory manuals.

If you can find a source for the PDF's get the corrected and index ones. I had to correct a few pages in the ones I have and tweak the indexes.

Also the parts catalog that www.clarks-garage.com mentions.

nothing is perfect...Haynes calls the cruise control (Tempostat) a 'thermostat' in their schemetics

FRWilk has good info from an 'early' owner's manual

oh...I just found this post too regarding the fan relay:

When you go to replace your relay, be aware that the factory documentation is wrong.

Most parts places will sell you the wrong relay. In fact, if somebody has replaced the fan relay with the factory reccomended part, that could be why only 1 fan is running.

pull the 1st and 3rd relays http://www.frwilk.com/early944/misc/relay.htm

Grab a flashlight, and count the copper contacts inside the 1st and 3rd sockets. The first socket should have 6 contacts, the correct relay part number is: 944.615.113.01 The 3rd socket should have 4 contacts. the proper relay part number for the 3rd position is 141.951.253B

The factory documentation has these relays switched. The reason i say count the contacts, is that it could have been a mid-model change in the early cars. I know of at least 4 cars (mine included) that the above information is correct. BUT.......it is possible that in very early cars the factory documentation is correct. Please reply with what you find out. I am trying to figure out whether the documentation is wrong for all early cars, or just a select group of early cars.
