Is there any chance that i could get a wiring diagram for a Volvo S40 1998 or any that hasn’t CEM in it. The oldest S40 wiring diagram that i have founded was from 2000 but there was CEM in it so that isn’t that useful for me at this moment.

Harold Muller says:

My 1995 Volvo 960 clicks under the shifter every time I press the brake pedal. I think it’s a bad microswitch. Does anyone know exactly where the two wires coming from the microswitch attach? The two posts coming out of the top of the microswitch have No wires attached to them. They must have been removed at some point. I’m assuming the shift lock solenoid works since it clicks everytime I press (or maybe release?) the brake. The car shifts out of park just fine. The clicking is driving me batty!!! Help!

I need the wiring diagram for volvo 850 1995 for the air pump, my car has it missing and after getting a used one with the harness attached, I cant find the same wires on mine.

@ Rich Buck. The seats should be just “plug n play” and all you have to do is put in a 30A & a 15A fuse in no.5 & 24 fuse section. Hey Presto!, You hjave working seats! That’s all I did after swapping my “keep-fit” seats for electric seats.

Not sure if this is available, but in the “2000 S70, V70, 2000-2004 C70 Wiring Diagram PDF”, there is a fold out Component list that is missing at the end.

It is in Page 2 (Page 10 in a viewer) as the very last thing in the book. If anyone has this, I would really appreciate any information on it.

One tiny bit of feedback:
The document named 2004.5__S40_V40.pdf is about S40 and V50, not V40.

How do I wire my 2001 volvo v70xc to tow a small boat trailer and what converter box would I need?

I’m not clear as to why you do all this work and it cost me nothing but I am really grateful that this information was so readily available. Working on a friend’s Volvo and I know nothing about them. Just trying to get him and his family back on the road. Thank you very much for the help!

Is it possible to have one apart from main-dealer network?

Dear Matt, any informations on ECU replacement for 2008 2.0D C30 would be much helpful for me. Where to find one of those witch one fits?

Hi Matt, many thanks for your website. I’ve spent countless hours trying to troubleshoot a faulty ABS circuit on our beloved 940, and got no where, until I found the wiring diagrams above. Problem solved in under two hours. This has been one of the most useful resources I’ve found in much web surfing.

Again many thanks

hi, i’m looking for the s40 1996 wiring diagram, thanks

Downloading 2003 s60 wiring diagram (thanks!!).
So I have fuse f24 (passenger comp fuse box), keeps blowing, disabling DIM and climate control, and electric seats. f24 is supposed to be ‘expansion relay 1’.
Seems to blow when I accel from 0 to 20mph (some short in some tranny switch? turbo switch?), or just coincidence.
2 days before that, had to ford a deep puddle. before that, had left the car alone for 6 weeks, and was getting ‘alarm service required’. After the fuse blew the first time, I am getting ‘srs service urgent’. any ideas? shoot..
