Want to run your AEM powered DSM in speed density mode but don't want to hack your wiring harness to death, here's what I did.

Parts required:

1 MAF-T male connector
1 MAP sensor of choice
1 AIT sensor of choice
Extra ECU pin connectors
Extra wire and loom
1 ignition timing terminal connector cover
1 tap and spade connector

Start at the MAF-T connector, remove the existing pins from the connector with a paperclip. Connect a new pin connector to the 5v power from your MAP sensor and insert into MAF-T connector pin 4 (green and red wire on harness side).

Next connect new pin connectors to both AIT + and - wires. Note: (For AIT sensor, polarity does not matter)

Insert the + from the AIT into pin 8 (green and orange) on the MAF-T connector and the - to pin 6 (green and black)

Then take your ignition timing terminal cover, remove the pin that lines up with the male side of the connector. Install a new pin connector on the MAP signal wire, insert into ignition connector.

Lastly and the only splice I had to make, take the tap and spade connector, place MAP ground wire parallel to the T-POS sensor ground and splice.

Note: It is an excellent idea to have all your sensors in place so you know how much extra wire you will need to use. This is because the flying leads that come with these sensors barely give you enough wire to hang yourself with.
