I'll try a full write up once I get around to installing, but for now I found a way to get that tricky second MAP sensor harness (sits on the passenger side of the intercooler) unplugged. No bumper removal necessary
There is a small black shroud that sits in-between the front bumper and intercooler on both sides of the intercooler/bumper. Once that shroud on passenger side is removed by hand, you can see and access the harness on the intercooler to get it unplugged. I've uploaded a video where I tried to explain getting that tricky harness unplugged. Hope it helps:
In this video I try to explain the simplest way to unplug the 2nd Map Sensor harness which sits on the top passenger side of the Mazda CX-5 Turbo intercooler...
