Hello all

I am having some trouble trying to get my reverse lights working, I put a newer tb42 efi in my gq which is the same as my old motor but I have also replaced the loom with a auto loom due to my old loom being shagged. I have power to the sensor thing on the manual gearbox and power to the relay but for some reason the relay is buzzing when in reverse, I don’t have any power at the reverse light though
I’m not sure what the deal is and having some drama with tracing all the wires, I know that the reverse light wire is green/white and the same on the relay. I was wondering if there was any wiring that runs into the cab and has to be plugged in somewhere or bridged into something. I know the the loom runs along the passenger side chassis and goes under the passenger seat but I didn’t want to pull it all out for no reason so I thought I would ask before doing that


So my question is
Why is the relay buzzing and how do I get the reverse lights to work
