04 S80 and XC70 part interchangeability

[P2metoo]

Hello!
Volvo pickings / junkyards are pretty slim near me and someone is parting out an 04 S80 (T6) with only 130K miles. Said electrical system was sabotaged / cut. Are there interchangeable parts worth looking at for my 04 XC70? No current issues in my ride, but something will come up as I try for 300K miles (another 15 years for me).

Coil on plugs, throttle body, VVT solenoids, brake booster check valve/vacuum pump switch, turbo control valve, boost absolute pressure sensor (located at the intercooler outlet), fuel pump control module (hard to reach near the front of the fuel tank on the passenger side), HVAC blower fan and resistor set, HVAC air quality sensor if equipped (easy to get if you pulled the blower), alarm module behind the passenger headlight, headlight switch module, fuel door lock motor & pin, heated seat control modules (under the seats)...
Memories of all the electrical problems I've fixed on my XC70.

Edit: I thought of another sensor that is good to have spares: transmission speed sensors but I think they match only on the 2.5L engine and 5-speed transmission combo. https://www.fcpeuro.com/products/volvo- ... c-30713952
