Adapting OEM Backup Camera to Pioneer Unit

[SoCal4Run]

Alright, now that I have the camera fixed, looking at adapter for steering wheel controls. Thought I didn't since my 4000nex came with remote, but the control capability of the remote is horrible. So looking at the ASWC-1, but also saw an adapter for toyota. Anyone else use this? Would like to not splice wires if possible. Thanks.
