Wiring Diagram 98 S70

Discussion in 'Volvo S70' started by Hamish Alker-Jones, Jul 22, 2004.

  1. Greetings

    I was wondering if anyone had a copy of the wiring diagram for the 1998 S70
    that they could either send me, or point me in the right direction to find?

    Many thanks

    In an earlier contribution to this discussion,
    I'm afraid it ain't as simple as that. Unlike the cars of yesteryear, it
    isn't possible to represent all the electrics for a modern car in a single

    If you can get hold of a Haynes Service and Repair Manual for the 70-series
    in Australia, you'll find about 16 pages of wiring diagrams. The manual I
    have is No. 3573 - but that is aimed primarily at the British version of the
    car, and it might be different in Oz.

    You can by a boo from Volvo with the complete wiring, its around 100 pages.
    What part of the electrics are you interested in?

    In an earlier contribution to this discussion,
    The above link *may* help but, AIUI, there were a lot of electrical changes
    between the 850 and 70-series in addition to the cosmetic body changes.

  6. Good point.

    I was hoping that by some point of luck there would be on some "hidden" site
    that I could access and and select the bits I am after while I wait for the
    manual to turn up.

    I should have explained that I was curious to see where the wiring loom for
    the towing electrics comes in, and where I could get a feed (with extra
    fuses) to have a power outlet in the boot.

    While on the S70, do you have a full size spare or the space saver in the
    boot? I'm looking at getting a steel rimmed 940/960 so that I continue on
    my merry way if one becomes damaged. My sister in law has the LPT S70 and
    has a factory alloy (16") in the boot, so I guess a 15 " will be of no
    problems. It measures up.

    I was having trouble connecting to the volvo site that I think you are
    referring to and have a manual on order, though it was mentioned it will be
    a while.

    I'm putting ina tow-bar and would like to have a power outlet 12V in the

    Also, any idea to increase the headlights performance? I was keen to wire
    in some extra lights, and have aligned the lights, but would prefer a tad
    more "spread" on the road.

    I found this one before, but wasn;t sure the difference between the wiring
    looms for he S70 and 850. It does have some good info though.

    Many thanks

  9. One I notice straight away was there is actually a switch in the seat belt
    to turn off the seat belt warning light. Ours turns off after 8 or so sec
    and doesn't appear to have any wiring going to the actual seat belt clip.

    Some good info though.

    In an earlier contribution to this discussion,
    When I wired my V70 for towing, I used the Volvo kit (which I think is the
    same for S70 and 850s) which made life very easy because it has
    plugs/sockets which plug straight onto the wiring harness. You have tgo be
    bery careful how you connect some of the lights so as not to upset the bulb
    failure detection device. The kit does it by providing a "sandwich" which
    plugs into the harness next to the device.

    On the V70 at any rate, there is a connector near the rear lights with a
    very hefty live wire in it which - by default - is only used to power the
    window-mounted radio arial. You can use this as a live feed for other
    My V70 was supplied with a "space-saver" spare - but the spare wheel
    compartment can easily accommodate a full-size spare. I bought a second-hand
    rim from a breaker's yard (alloy to match the originals - but I would have
    settled for a steel one).

    Not all variants use the same wheel size. Mine are 195/60x15. Some cars use
    16" or even 17" wheels, usually with lower profile tyres - so the overall
    diameter is similar, but the width may be greater. Try one of your road
    wheels in the compartment and, if it fits, try to get another one the same.
    Be very careful if you buy a wheel intended for a rear wheel drive car -
    because the offset may be different.

    If you want actuals and much more and do a lot of your own mtce., try
    this site and pay a nominal ($20?) annual fee. I use it regularly.
