Cable near gearbox

Good Evening Yet Again

I notice on my herald there is a pair of wires coming from where the gearbox is. There are green and green brown. See attached photo. Any idea what they are for.

Thanks in advance

They are for the reverse light which is operated by a switch on the gearbox. Does yours work? If not its likely those two wires need to be plugged in to the same colour wires in the loom unless they were left disconnected for a reason😲 

Perhaps best to put a meter across them on resistance (checking theres no voltage to start with) where the reading should be high until you select reverse and then you should have zeroish.

Probably had a replacement gearbox from a different car possibly spitfire as those would be reverse light which I don't believe Heralds had

you havnt got an overdrive lurking under there ??

yes without looking at the wiring diagram the only circuits looped in through the tunnel is reverse lamp switch or overdrive supply

Thanks all. My  job for the weekend to check out. It would be good if it had overdrive as it this is what heralds really needed. If it has then will need some further advise on switching and wiring. A question for the future.

green/brown was for the  reverse lamp switch
