M3 swap wiring questions

[bonbonb]

Just dropped the M3 S50 in the other night, got few questions wanted to ask just to be sure.

Top red wire is + from battery, second red wire too? Bottom black is ground, right?



There are three hoses go to the throttle body (I know picture is showing only 2) which one first (closest to radiator)?




Thank you.

Both the red lines are for power and both need to be on the positive terminal on the battery. There's a place for the ground to go behind the shock tower. As for the coolant lines that go to the throttle body take the sensor looking thing off and loop the lines on the throttle body. All that thing does is heat the incoming air... it's useless.
