Is there a source for some large readable wiring diagrams for a 1993 model 240? I need something better than the CHILTON books.

 

the 1993 is fun because they made some fairly major electrical changes late in the model year, so there's two different versions. the late 240 has a multi-fuse block right on the battery + terminal, thats the best way to tell them apart.

the best wiring diagrams are the ones from the original Volvo "greenbooks", which are no longer in print. these are available on a DVD-ROM from Volvo Owners Club (VCOA), covering nearly all years of 240's.

the drawings in the chilton, hayes, and bentley books are nearly unusable.

 

Try this link. It includes the 1993 model.

The greenbook 'TP32352-1 1993 240 Wiring Diagrams.pdf' there is the 'late version' with that aux fuse holder on the battery + terminal.

the other 1993 diagram there is from the mitchell service, whihc provides independent mechanics with tech info on every car ever made. their drawings are not very well laid out nor do they show the connector locations like the greenbooks do...
