Engine harness wire(s) identification

[RS12Turbo]

I was cleaning up my wire the other day on my ca-to-s12 swap, and was wondering if anyone knew off hand what the following wires are for, and if they need to be hooked up. My car has been running since Jan with no probs, but I was just curious if these should be connected.The location of these wires come off of the 3 engine harness plugs near the maf location.Colors:

grey/ yellowblue/ yellowblue/ redblue/ whitesolid greygreen/ orange

Thanks
