Question about voltage limiter

Thank you everyone
Someone played"pimp my duster" with this poor car and I've been chasing electrical Gremlins for weeks now and this will be the third time the instrument cluster has been out in as many weeks, but third time's the charm..... Right?
Would you believe there were 8 interior lights in this thing along with a homemade console ?
Good news, it seems the original back seat frame is under all this velour and faux leather
Here's a pic...... I know it's an abomination I especially like that old belt door pulls

I had called advance auto, AutoZone and O'Reilly's. The guy from advance knew what I was talking about(he's a fellow Mopar guy) but couldn't get one, was going to try NAPA monday, but decided to go with the one from RTE since it's a solid state replacement, about the same price and hopefully will never need replaced again

BTW, anybody need about 50 feet of assorted lengths and gauge of orphaned wire
