Mopar part number:  4414821 - Alternator (negative battery) wiring harness.
 
This harness fits:
 
1988 2.2 Turbo (fits both turbo I and turbo II) - Daytona, Shadow, Reliant, Lebaron, or New Yorker)
 
And here's the really cool part...
If you are installing a Super 60 Mopar Performance engine wiring harness in your 86 or 87 GLHS....this is the alternator harness you need to plug into your Super 60 Mopar engine bay wire harness.   If you are lucky enough to have an S60 MP engine bay harness, you know that it doesn't come with the alternator harness....    this is the alternator harness that mates up to that S60 (SMEC style - L body) engine bay harness.     We only have 1.  It is brand new Mopar as seen in the pics.
