Default LS400 Fusebox

Anybody had any trouble with the fuse box?

My '92 LS stops running once in a while if I hit a bump and other times doesn't want to start. I can reach around the fusebox, the one beside the steering column, and wiggle the large wiring harness and it will start. I can hear a relay clicking as I move the wiring around. I also have been having trouble with my A/C and radio not working too. Again, moving the wiring around connected to the main fusebox will bring that back to life. I think my only recourse is to replace the fusebox itself. I'm hoping I can get a little input on this from other LS owners so affected?

Thanks!!!

You could probably repair something like that quiet easy if you are handy with a soldering iron and shrink wrap. Upon removal make sure you take off the negative battery terminal to make sure the arcing doesn't cause anymore harm.

Just as a follow up:

I replaced the fusebox this morning and all my electrical problems are now history. Everything is working as it should! The old box looks good on the outside but I suspect it is toasted inside.
