Can I run two new wires for thes sending units as they are missing and if so where and what color do they connect too ? As I’m installing Ralley pack gauges but missing the wires under the hood ? Thanks

 

The blue and green wires were in the factory harness originally. They are the same wires used by the idiot lights. These wires are in the engine harness part of the firewall connector.

 

Series 56 male terminals. You can get them at Napa pretty cheap.

Take a closer look at the firewall connector. Unless someone took the time to remove the connector body and remove the wires from the housing, I bet they are there. Unless the cut them flush with the housing?

 

Thanks Joe,
as soon as I posted this I was tugging on a blue and green wire and
they both came out of the firewall capped off and ready to go right where I left them about 10 years ago lol 🤣😂🤣 thanks for the quick response !

 

They were there right where I left them 🤣😂🤣
