Contour Enthusiasts Group Archives Forums Modifications Audio which harness to go back to factory premium sound?

I'm thinking of trading my car in and would like to take out my current stereo and put the original Ford stereo back in. I purchased a Metra 71-5600 harness, but the square part does not fit into the back of my stereo. The narrow, rectangular piece fits fine. Can someone tell me which harness I need to purchase to go back to stock premium sound setup? Thanks.

do u have the stock amp setup. thats the wrong harness. 71-1770 is to make the harness stock again. 70-1770 plugs into the stock harness when adding aftermarket hu.

Are you looking for this?

or this?

what car do u have. the one i listed is the correct harness

71-1770 harness

That 71-1770 harness won't work for premium sound head units. The audio output connector is different.

whats premium sound? amped?

Premium sound is with the factory amp. 71-1770 will not fit. Maybe I'll just take out my Pioneer speakers and replace it with stock and just leave the HU alone.

Was the amp cable cut during the installation of the new head unit?

hhmmmmm, i dont know then. everything i see lists the 71-1770 is stock replacement and 70-1770 for adding aftermarket hu's. my svt has an amped stock hu. the 71 is identical looking to my stock plug. and the 70 plugs right into it perfectly. hope someone else can answer this for u then.

Yes, the amp cable was cut during installation. Everything was cut and spliced back together, even though the amp itself was not bypassed. I won't bother with the HU. Thanks.
