Tried a battery disconnect and earth?

Tried disconnecting battery negative,leaving for about 5 min and reconnect, no difference

The wires that you cut/spliced - were they definitely ones from the trailer ECU to the plug? not Trailer ECU to LCM.

If you have no lights its either a fuse or the LCM. Try unplugging the trailer ECU.

Quick check; there are 5 fuses in the passenger compartment fuse box associated with the LCM headlight function (4, 9, 53, Link3, Link4). The LCM uses MOSFETs to individually fuse each circuit. Are any lights working? I can't see how you could possibly fry the LCM - trailer ECU maybe.

As to the static, it's in the passenger side? there's not something crossed over to the reverse sensors? whats the chance you have a scanner to see if anything is crying?

Given that the plug has been changed, someone has been playing before you, and what creative things have been done, well...
