Reversing light switch position

[Evo1972]

Hi all
Quick question and probably a silly one but where is the reversing switch on the gearbox on a 70 us import. Been under the van this morning but buggered if I can see one. Was going to wire up reversing lights as PO had used rev lights as indicators but I've changed to european spec rear lights with the indicator in.

Not all gearboxes have them fitted but as above right at the front on the nearside and hard to get to
