I am planning to purchase a used gauge panel with speedometer,tachometer,and a fuel gauge from a junk 240 GL which Im planning to put into my 240DL 1990 with large clock, speedometer and a fuel gauges on it. If I install the one with tachometer will there be some wiring modifications since I have a clock on mine instead of tachometer?

Also are steering wheel of these two models intechangeable. I like the one on the GL because its smaller than on my DL.

Depending on the year of the donor car, the speedometer may not work. Volvo switched from a cable driven speedometer ('85) to an electronic speedometer in '86 I believe. Your '90 needs the electronic version. The tachometer will swap right in to your present instrument cluster as several have said. I did it on my 240 and it works fine. A nice upgrade.

I also have a 1990 and am considering the purchase of a 1985 turbo gauge set. I'd like to have the tach, but I am also very interested in switching the oil temperature gauge as mine is basically defunct. Anyone know of any issues with such a switch? Thanks in advance!

With the 90, you should have the airbag steering wheel. You can't put in the smaller steering wheel unless you are willing to lose the airbag. If you don't care about the airbag, then I think the smaller GL wheel will fit, but I am not positive. You will have to remove the airbag contact reel.

Luis:

This may be what you meant, but it will be far easier to just remove the tach from the other gauge panel and install it in your existing panel, rather than swapping the whole panel. When you remove the panel from each car, you'll see how easy it is. The tach and clock both are removed with a few brass hex screws, sliding straight out the back over some straight electrical terminals.

As was already mentioned, just connect the loose red/white (red/grey on some) wire to the terminal at the bottom of the tach. If there are two terminals at the bottom, it doesn't matter which of the two you use.

Best of luck.

No, it is the easiest gauge to install and you have the red/white wire to do it, already in your dash. Just do not plug that wire into anything but the lower terminal on the tach. The upper three prongs are for a harness to run a ssmall accessory clock.

Ther is no difference in steering wheels from DL to GL. The same wheel was used unless someone has installed an odd one. The 89 and your 90 (?) have the weird non-airbag wheel that was used only a year or two, I think. 89 for sure, but maybe you have a bag? Anyway, there never was a DL/GL difference.
