S13SR + reverse lights

I know this is a common thing when completing an SR swap, but my reverse lights do not work. I was under the impression that it is controlled by a sensor on the transmission that has to be swapped over from the KA… am I on the right track?

Hm, alright then the sensor from the SR tranny should work. Ill go back and check my wiring. Thanks

This pic is from the KA FSM but is the same on the SR
minus the SR does not have 4th or 5th position switch.
