Need help finding correct pigtail please. 2006 Lincoln Navigator with THX system uses an 18 pin connector for most of its speaker outputs (to amp) from head unit in addition to a 24 pin connector. Able to find pigtail to connect to 24 pin connector ((Metra 70-5520) but having trouble with findng counterpart for 18 pin. I believe the existing ford connector (the one I'm trying to find a pigtale to mate with) is Motorcraft WPD-279 https://www.amazon.com/Company-Motorcraft-Anti-Theft-Connector-WPT-279/dp/images/B009FXEZ3G

Does anyone know where I can find a female pigtail which would connect to the male WPD-279?

Any help appreciated.

Are you trying to retain the OEM head? Try Metra kit 71-5520

Nope - replacing head unit, but trying to keep factory amp/wiring.

Hi,
The connectors are manufactured by Molex. They're called 'H-DAC 64
Dual-Row High Density Automotive Connectors'. They do show 18 pin housing with male pins, however they are meant to be mounted to a circuit board. They don't show a housing with wire-type termination for 18 pin applications. If wires were desired, they'd need to be soldered to the header pins and of course insulated.
Hope this helps,
Mark
