    The "extra" sensor can be left tied to the loom. I believe it's ambient air temp but I need to look it up to be sure.

    The triangular connection is a CAN bus connection. You can leave it plugged and if someone needs to hook a service tool to the engine, they have that as an option. I'm using mine to connect to my transmission controller CAN bus.

    The yellow plug can be left alone. I believe it's two CAN wires, maybe a charge lamp indicator, and a jumper to the AC compressor plug that's also on the harness. This was leftover from an option for an OEM connection point.

    What are the extra plugs for?

    There are some extra plugs on the engine harness that I can't find an explanation for in the install manual. I assume 2 of them are extras for something not included with the R2.8, but the 3rd I'm not sure. There is also a extra MAP sensor. Can someone confirm this is to measure ambient pressure? Do I leave it zip-tied to the loom tube or mount it? Should it have a sintered or foam air filter?
