I scored some nice tricks for a late 240 at Crazy Ray's today in Jessup, MD. Now I need help in figuring out if I can use them all. I got the mini-tach that was in the top left spot above the center vents. I also got the three gauge cluster that slips in to the right of the tach, with oil pressure and volt meter gauges. Here's my question:
1. Are all 240's wired for the tach?
2. Are all 240's wired for the volt meter? I expect the oil pressure meter needs a special sending unit, given what I know about the stock sending unit.

The donor was a sweet 245 with 5 speed manual that looked like it was given alot of love before the accident. Black leather interior, dark red paint, all the options inside. Someone's loss, my gain. I also scored a pristine tan center console with seat heater switches for my daughter's car. Well worth running around in the cold for an afternoon.

Thanks in advance for any help on the gauges.

The only accessory 240s are "wired for" is the big tach that goes in the main cluster. But in general, ground (-) is found at the center console frame, you take power (+) from a fuse that turns off with the ignition, the brown dash wire is for instrument lights. "G" is for the wire from a sender if any (oil temp, pressure, etc.). The tach needs a wire from "1" on the coil.

Thanks for the explanation. I might put the voltmeter in the single pod to the upper left and sell the rest of the gauges.

A voltmeter is nice, I just installed one myself (new from the dealer, it was actually not expensive, and came with a complete harness). Installation is a straightforward job even if you have to make your own wiring harness, but if you need any hints here are the original instructions:

Out of curiosity how much is a voltmeter from the dealer. I can't stand calling the volvo dealer here; it is operated by a chevrolet dealer.

I think I paid a bit less than the equivalent of 50 US bucks for the pleasure of lifting the meter out of a blue box. You might think this is far from "not expensive", but please keep in mind that price level in general is a bit higher here in Norway than in the US.

Cool reference. Thanks alot. I'll definitely use it when I install the voltmeter.
