DIY: Aux Input Jack Adapter

Saving this DIY from the Hack credit to IsLNdbOi

*SOLVED* Connecting stock aux jack to RCA cable. *SOLVED*
I would like to be able to use my stock aux jack with my Alpine HU. I have the adapter for the Alpine so that I can connect an auxiliary source to it via RCA audio cables (red / white cables).

I cut my stock aux jack and the end of the cable I had (3.5mm to RCA cable) and stripped the outer jacket. Here are pics.:

See First Picture

The end on the left is the 3.5mm to RCA cable (chopped off the 3.5mm plug) and the end on the right is the stock aux jack.

The RCA cable has two black wires, a red wire and a blue wire. The stock aux jack has two red wires a gray wire and a green wire.

To get the aux jack to work, do I simply solder these four wires together (the four wires from the aux jack to the corresponding wires on the RCA cable)?

If so, anyone know which wire from the aux jack needs to be soldered to which wire from the RCA cable?

I found this page in the Yaris service manual too:
