What is the best way to do this? I could not get it throught the OEM loom, and my hands do not want to fit in there to be too precise with it. Any suggestions?

 

Remove the OEM groumet and poke a screwdriver or something else sharp through it on both sides (that way you can still put the groumet back in but the wire still goes through it). Then I have some shrinkwrap and I put both of the wires through that, the shrinkwrap is the same size of the factory wires, then I tie wrapped the shrink wrap to that factory wires. Tedious process but it works, hope this helps. Btw, I still doesn't see the 'www'
