On our F4s, there are two 'two pole' harness plugs.. one is white and one is black. The black one I know goes directly to the fuel pump. Where does the white one go to?

I have always wondered... I can upload a pic if needed..

thank you!

 

Wow.. apparently its not quick nor is it easy...

 

T, Sorry, I missed this somehow. Post that pic. Not sure which one you're talking about.

 

Here ya go.. the black one is the fuel pump...

 

That's your Rear Brake Light Switch Connector. If disconnected, when your rear brake pedal is pressed, the rear brake won't light up. Front brake control will still light it up though.

 

Thank you! Another mystery solved.

I was just curious about it lol
