How to fish dome light wire up there?

[davepl]

Subject line is it in a nutshell, but I need to run both the cargo and dome lamp harnesses up to their respective locations.

I put a big washer around it and tried to "drag" it up with a strong magnet, but that went nowhere fast.

I tried to send a wire down from the top hoping I could then tie it and drag my harnesses up, but didn't have much luck. Well, no luck to be precise.

Anyone done this before and have a trick to share?

Thanks!
