Just need color code for rear fuel pump. I have an orange wire brown wire and a yellow wire. Thank you for any help with this I believe the brown wire with stripe is the positive?

HI and thanks for using 2CarPros. Com.

I have attached a wiring schematic for your vehicle. I am seeing the yellow and brown, but not orange. There is a red. Is it possible what you think is orange is a faded red?

The only other way it makes sense is if you have the 460ci engine. Then there is an orange wire. You did not indicate an engine size so I am not sure what you are dealing with. The second picture I attached is for the 460. This schematic shows an orange, yellow/light blue, and brown/white.

Take a look at the schematic and let me know if it helps. I have a feeling you need picture 2, but not completely sure.

Take care and let me know what you find.

Joe

I actually figured it out but yes it was a 460. My first time using carpros I will definitely keep this handy. I like the support and information I am seeing. Thank you Joe for getting back to me.
