98 Jeep TJ 4cyl fuel pump wiring?

[KarlVP]

Trying to wire back up my fuel pump after relocating the stock tank. The stock connectors are gone.

From the chassis wiring I have 4 wires.

Blue with green stripe
Green with white stripe
Black
Black with yellow stripe.

At the Tank I have
Orange
Black
Red with black stripe
Black with green stripe.

I need to connect them together.

Responded on PNWJeep too.

I pulled up a '98TJ 2.5 wiring schematic, it doesn't give me different colors at the connector, it lists same colors on both sides. Here's what I got, hopefully it helps.

Your dark green/white is fuel pump power from the fuel pump relay.
Your Black is fuel pump ground.
Your dark blue w/ light green is fuel level sensor signal to PCM.
The wire your're calling black w/ yellow stripe this shows as brown with yellow stripe, and it's fuel level sensor ground to PCM.

Is the tank/sender still out of the rig where you can figure out which wires go to where? Pump power, ground, etc?

Karl, I've got the Chrysler factory repair manual at home. IF you don't have the answers by tonight, I can look it up. It should not only have wires by color, but also the connectors pins by location.

That's what we got figured out. Tested by jumpering leads. We then flipped the tank upside down to test the fuel level sender. PS. Put a catch can there or you will get gas everywhere. :awesomework:

We relocated the factory tank to right behind the seats. Photos will be up on the build thread tonight.
