wiring diagram needed, Fuel pump relay trigger
I have diagnosed my fuel pump relay issue to be the trigger, or rather lack of.
I am after a wiring diagram or info on the Gn/Be (green wire with blue trace) that goes to Pin 86 on the Fuel Pump Relay, the basic diagram I have says it goes to the ECU for a ground/trigger, but assuming it should go to the bosch ECU behind the relay - I am not seeing a Gn/Be wire in that loom, perhaps it goes via a connector and changes colour? - But I have checked all the connectors nearby and it doesn't appear there. A little stumped, because the shortest route to the ECU is direct but its not obvious, without stripping back all the wiring looms to find its route I'm not convinced it goes to the Bosch ECU HELP please Everything is testing OK, voltages good, both Pumps work, its not the relay, the relay triggers if I Ground the Gn/Be wire, so I'm looking for any info on its route to where? |
