It should be in the fuse box which is behind the front ashtray, just remove the ashtray, it just lifts out and the fuse box is behind it.

Fuel pre-pump is in the gas tank. That involves dropping the tank so you can pull the pump out and throw the new one in. I would just bring it to a shop unless you really want to do it yourself.

First used in February of 1977 on Volvo B21 four cylinder engines, the Lambda-Sond system was an emissions reduction system which used three key components working together: 1) Lambda Sensor. An exhaust gas composition sensor to monitor chemical composition of engine exhaust; especially NOx(oxides of nitrogen) and feed data to the engine control system. Essentially, an oxygen sensor positioned in the exhaust pipe before the catalytic convertor. 2) A feedback loop providing information to the engine control computer that enabled more precise control the fuel injection system. 3) A catalytic convertor. This system greatly reduced exhaust emissions while allowing much better performance and fuel economy. It proved to be a key to restoring the performance lost by the addition of emission controls on vehicles. It was the fore runner to modern electronic engine management systems that eventually appeared as similar systems on all automobiles.

Are you sure it is the Master?

I had this problem on my 940. It started as a slight shudder when I braked, and then there was an intermittent clunk. Then, without any warning, both of the front brakes fell off (Completely. They were dangling by their cables!). It turns out that the bolts holding the brake system on had vibrated themselves out. Try tightening the bolts and see if that helps.

I have a 2002 Sedona - after opening the drivers door turn your side lights back on you can then close and lock your car with the side lights on. Hope this helps.

I've had really good luck with the Bougicord brand, I believe that they are OEM.
