Hi just purchased a 2008 DB9 Le Mans edition non runner previous owner removed engine wiring harness,bought used one installed it ended up with spare connector had no clue where it went,I have the old harness but need to know the destination of pin outs to check what goes where all illustrations I have found show the harness but no labels or explanation what goes where,can you help pulled out what little hair I had left trying to figure this puzzle out as have never owned or worked on Astons before,also immobiliser will not operate possibly related to the harness Thanks Clive
Hi just purchased a 2008 DB9 Le Mans edition,non runner as original engine harness removed(fire damage)previous owner fitted new(used)harness from a Aston specialist,install harness only to find spare connector with nothing to connect it to,question would this stop the engine starting because engine will not fire and immobiliser is still on,hope to find engine harness that has been labelled but so far no luck,can find expoded views of the harness but nothing is tagged or labelled,could you push me in the right direction
Hi Clive,
I can’t be or much help I’m afraid, I’ve been looking for a connector location diagram and never found one.
What year is your new engine harness from, and can you describe the spare connector and its rough location.
Paul
Hi Paul sorry for delay been in Hospital and in recovery,so far I can only find one connector spare looking from front of car into engine bat it is left hand side between washer filler and left hand cylinder bank will try and take picture it is a fairly short lead which means the male connector must be nearby,as you know quite a tight bay to be poking around,I have dash working everything apart from fan/blower and blank screens within the main instruments Thanks Clive As you guessed I have yet to try and fire up the beast as just finished assembling top of engine,plugs and injectors want to make sure everything works before pressing the dreaded start button!!!
