2008 WRX - 14 or 20 pin wiring harness?

[scottyja]

I ordered a wiring harness for a new aftermarket HU from Amazon - Scosche SU03B

What was delivered was a 14-pin harness. Now I'm reading that 2008+ non-navigation headunits switched to a 20-pin harness. Even the crutchfield recommended harness for 2008 models shows the 14 pin. Will the 14-pin harness work or do I need to find something specific for the 20-pin? If so, where can I find this?

I haven't removed my stereo yet. I'm getting the new aftermarket HU delivered today, so was hoping to solder the harness to the stereo connection tonight. Now I'm worried this won't work out. Any thoughts?

Thanks.
