MyBrickIsSlow Posted August 4, 2015 Report Share Posted August 4, 2015 I am trying to install my Autometer Cobalt gauge in my 01 xc70. I need a 12v source that stays hot while cranking the engine but is switched off with the key out. I do have access to wiring diagrams but am unsure how to identify these circumstances in the foreign language that is a Volvo fsm. Could someone help me out here? This is my first P2, and I am still learning, so please lay off the "spoon feeding" comments. Link to comment Share on other sites More sharing options...
VolvoNor Posted August 4, 2015 Report Share Posted August 4, 2015 Easiest would be to tap into the ignition switch. I believe the green/yellow is constant 12V when cranking and off in pos I. Link to comment Share on other sites More sharing options...

MyBrickIsSlow Posted August 5, 2015 Author Report Share Posted August 5, 2015 I was able to locate the scenario i was looking for on the ignition switch, opposite the key. It is a blue wire with a red stripe. Link to comment Share on other sites More sharing options...
