Hey, You almost got it. Metr does make a harness set that bypasses the amp. It's Metra RoadWorks Ford/Mercury AW-WHFPS. It has the two connectors that you pictured plus a third double ended connector. One end fits into the amp and the other you cut off and wire to your speaker outputs.
Oh yeah, it cost me 9.99 in south Jersey at AutoZone.

Good luck
