For the MAF, pull some more of the wire loom off the wires. The wires are tapped together. Unwrap the tape and it will give you some more slack. If you want to keep the stock look, go to Advance or Auto Zone and get some more loom. You can use it to cover the wires you uncovered during the install. As for the coupler and the actual intake tube alignment, I would send those pics to Vik at FSW and have him take a look at them.
