Head Unit Install Question

I have my new head unit installed and buttoned up except for one single wire. This one requires a Pink (Speed Pulse Input) Connect to the vehicle’s speed pulse harness. Crutchfield says it's a red wire in a 17 pin harness connected to the ECM. I seem to have found this harness but there are two red wires in it.

Does anyone know the correct wire I need to connect to?

This is for a 99 LS without NAV or NAK.
