We now have a fantastic solution! These wiring harnesses are made to replace the damaged original wiring coming out of your Mustang's Heater Blower Motor case. They feature the correct colors, connectors and grommets.
The earlier (production before 4/1/65) style features the orange, red and black wires for the 2 Speed (3 wire) motor. This is part number WG7591.
The later 3 Speed (two wire) style has the correct yellow and black wires for the later '65's, '66's and '67-68 Mustangs. This is part number WG7592.
We are currently restoring an early Heater Blower Motor and will post pictures as soon as they are available.
