I replaced my HU with an Alpine 7893, and now my FM stations won't come in because the FM antenna booster is not powered up.

Does anyone know how to identify the power wire of that thing without having to trace it all the way back to the unit? (It's a PITA putting the trunk liner and all back together)

Once it is identified I will either run it off of the amp turn on lead or maybe a power antenna lead.

Thanks!

 

If you used the Metra harness plug, it's the blue wire. This diagram should be similar: http://www.installdr.com/InstallDocs...PDF/647021.pdf It's the 1995-1996 or newer plug pinout diagram.

I believe the radio harness plugs on Nissans hasn't changed since 1995 or maybe longer.

 

Thanks man, I'll try that!

 

I just hooked it up, and everything works great! Thanks for the tip
