10/4/2005 Pete Jr recalls the 66 GT has the Fog Lamp wiring built into the DASH & HEADLAMP wiring harnesses. So.. different part numbers. I hope this helps!

A 1966 Mustang GT, does it have the same wiring harness as a 66 Mustang V-8. I am specifically wondering how they handled the fog lite wires. Were they simply added along side the harness or was a different harness available in the GT with the fog lite wires inside the wraping? Need a little help here. THANKS SEE Y'ALL
