Temperature control unit blue and white wires
#1
#2
according to the real volvo schematics (I hate those mitchell things), MCC (manual climate control) pin 13 is a blue wire that goes to 5/1 B:1 via connector D1 pin 1, and MCC pin 11 is a white wire that goes to 5/1 A:5 via D1 pin 3. connector D1 mentioned above is a 4 pin block connector that looks to be right behind the MCC control panel.
5/1 is the instrument panel, connector A is behind the tach on the top, while B is below it, both of these are horizontal connectors. instrument panel pins A:5 and B:1 are the instrument panel and dashboard dimmable lighting circuit as driven by the rheostat
