If you are careful with the ribbon cable, there is no need to remove it, the fan will swing out of the way enough. I applied a small amount of sticky tape over the connector to keep it in place, just in case!

You can get the cable with or without the bracket and IR sensor assembly. Opt for with the bracket, makes it much easier.

** Note to iFixit, the install of the new cable would be much easier if the cable was pre folded where it bends up from the bottom where the two 3mm screw holes are. Thanks.

Warm the grommets with your hands for a minute, so they become more flexible, then using the Spudger to gently ease them in helps.
