Should be simple... Pics inside!
Anybody know what the weather pac / 3 wire loom above the rear axle is for???
It's on the rear half of the axle hump towards the bumper... It's not for the fuel pump... I'm thinking rear tail lights....?
I have one wire that stripped/pinched in 2 spots... (don't ask me how or why because its too high to get pinched???)
But I guess I'll be fixing it before I put my torque arm in.......
Any insight would be appreciated..... Thanks!

My take on that connector, is that it's connector 313 for the fuel pump, as all the rear lighting electrical comes through the drivers side internally!!

Connector 313 shows only one tan wire for the fuel pump in the schematic, but the connector face drawing shows 3 cavities, 3 cavities means three wires!!

One for pump power, one for the gauge, one for ground????
last time I remember being under the car at that spot, that was the connector that I was undoing for the fuel pump!!

Correct me if I'm wrong!!!

That's the connector for the fuel pump/sending unit. Combines fuel pump & fuel level signal

I know, was just confirming your post
BTW, nice to see the "toothpick" still in place. usually those are gone whenever someone (mechanic) disconnects the connector and throws it away

Re: Should be simple... Pics inside!
Thanks gents........hmmmm I'll have to take another look....
I've never had trouble with my fuel pump or sending unit, but if you're right I guess I've been lucky!!!
I was hoping that it would be for my tail-lights as I keep blowing fuses for my brake lights (even though my running lights stay lit....)
I hate electrical problems!!!!!! grrrr Thought that I had figured one out!!!!

The harness for the lights runs inside the car along the drivers side.
