Hi,

Oh ok i think i know what you mean.
Its another three nipple tube end right?
I’ve been driving a Volvo long before anyone ever paid me to drive one.
That's probably because I've been driving one since 2015 and nobody has offered to pay me yet.

No cap on the interior end. Just Take a wire and fish it through. It's quite easy you'll find.
When I was done running wires through mine, I left an extra wire loose in there for pulling any future wire(s).

Mine had a cap on both sides. If you have some semi rigid but sill flexible wire it will help a lot with pulling wires through.

Oh ok yes, i think i may have something.
I hope the 'tube' does not bend too much through makes it harder to get through.
I had an electricians fishing wire but not sure where it is now. I probably have something laying around though.
How long do you think it has to be? like 1 foot, 2 feet, etc. ?

Something like one of the wires stripped from a piece of household Romex will due. 12 or 14awg. 2' long is plenty.

Oh ok sounds good. I also have a piece of thin spring steel wire which is stiff but still bends. I bent a closed hook at the end. See if that works. It's about 3 feet long. Lucky i could still find it havent needed it for anything in 20 years.

You could also attempt to tap into the battery/memory terminal on the back of the radio...

Ok another problem as usual with this car.

The nipple cap in the inside of the car will not come off.
It's very hard to grasp too, i could only get my hand in there enough to grab the nipples. As hard as i pulled it would not come off.
I need the entire cap to come off as my wire is thicker than just one single wire.

I had trouble with the one under the hood too but i think i can get that one off it seems loose. The one inside seems like it is glued on it wont budge even a little. May even be molded on.

Any ideas?
