st4stokie 10 Posted October 18, 2013 Does anyone have a wiring diagram for the large round multi pin plug in the engine bay on a late VR6 please. There are two blue wires on there I need to identify (they are both the same colour with no other markings) Quote Share this post Link to post Share on other sites
J.C 10 Posted October 19, 2013 I've just looked at the Bentley manual, known to not be 100% correct for our UK cars. but here goes, T42/21, blue on car side, brown/grey on engine side, goes to the Intake Air Temp. sensor (IAT) T42/22, blue on car side, Blue on engine side(I think), goes to the engine coolant temp. sensor (ECT) Quote Share this post Link to post Share on other sites
st4stokie 10 Posted October 19, 2013 Thanks that will explain why the car ain't starting since renewing the plug terminals. Obviously got the blues the wrong way round when reconnecting. Thanks again for the info it's much appreciated Quote Share this post Link to post Share on other sites
