Hi i am doing a corsa b c20xe conversion and i have the wiring loom, i have also brought a 15 pulse transducer to fit onto the gearbox speed reader to convert the mechanical energy into electrical i am assuming it does that. but all the threads i have found with regards to this all have a certain orange connector wired into the loom, mine does not have that in it. How and were do i wire it up to? any adive would be much help and pictures even better.
