How to get reverse light to work after T5 swap?

Something I haven't messed with yet, though I really should. After I swapped my T5, I attached something from the 4spd onto the T5 of what I thought was the electrical connection for the reverse light. Right now mine does nothing when I go into reverse. I was hoping to fix that.

Does anyone know what I need to hook up where to get it to work? Sorry for the lacking of details, but it's been a while since I did the swap so I can't remember exactly what was done.

I'll try to do some searching under the car again soon to give more details if it's needed. Thanks for the help.

double check your connections and the fuse. when i did my t5 swap the electrical harness plugged right up, no mods involved

did you use a t5 electrical harness or the same one that was hooked up on the 4 spd?

i may need a t5 harness if it's not the 4spd one. i only got the transmission, no wiring stuff.
