I am in the process of making my own plow harness and I need to get the connectors for the headlights. I have a 89 f250 with 9004 bulbs. I was able to get one connector from the parts store. however I need the mate. the connector that would look like the bulb

 

Go to your local Junk Yard

 

what vehicle will have the female end. I already bought 2 new male pigtails at the store , just need 1 female connector

 

that'll be a tuffy. you may have to buy a few headlights to pull apart and use. i wouldn't imagine you could readily find the female part.

a trailer harness or something to that effect may have been your better choice.
