Does anybody know where i can buy a replacement wiring harness that goes from the front and includes the fuel sending unit plug? Its not the harness that has the rear tail lights but another one that I'm not able to find.

Thanks

Well, your problem is the fuel sending harness is part of the taillight harness. Nobody offers a partial harness. What's wrong with your wiring?

I recently installed this wiring harness on my 68 coupe:

WIRING, TAIL LIGHT HARNESS, 1968, COUPE & CONVERTIBLE :: Wiring Harnesses :: Electrical & Wiring :: Mustang Parts & Accessories Superstore - 1800Mustang

There is no connection for a fuel sending unit plug. the only connections are:

1. 2 X taillights
2. license plate light
3. 2 X back up lights
4. a ground wire

It has been a while since i was underneath the car but my current fuel sending plug come out of a hole on the passenger side of the body, leading me to believe it is somehow attached to the interior lighting harness, but i cannot find any comfirmation of that. nor can i find a replacement wire.

Bump. Anyone have any knowledge about this? The yellow wire in the pic is the fuel sending unit feed, it travels up through the trunk and the up behind the passenger side wheel well. I'm asking what wiring harness this wire is a part of.

On my 68 it is part of the harness that travels down the passenger side of the car (under the scuff panels).

I could not find this harness repopped. I had mine restored.
