The 05 is obviously different than my 99 and 02 were and I don't know which port to plug the controller in. If I remember correctly there are now 4 on the top instead of 2.

Can anyone tell me the correct one to plug into?

Thanks.

I believe it was on the bottom left. The connector only fits in one place.

In the black plastic box about where your left foot would be. Should be the top left plug space. NOTE: They changed the pin locations on the plugs in 03 so if you are using the same harness from 02 or earlier, you will need to make pin changes on the harness or use the new harness that came with the 05.
