Is it doing it sitting still or driving it?

Have you checked the plug on the headlight switch? It is has a noted problem of burning out terminals.

it will do it sitting stillor driving after putting on all the extra the grounds it is not as bad but it still has a noticable flicker when driving and sitting still at idle it seems to go away when i load the engine like you would to bring up boost ?? the head light plug is fine and the switch also looks fine and i just replaced it a month ago

Try a genuine MOPAR regulator - you can probably pick up 4 for $20 at your local automotive recycling facility.

i actully tried that i pulled the reg off of the 82 crew cab it looks the same voltage is the same on the guage in the dash the reg from the 82 has the mopar logo on it

Go to a Dodge parts-counter and get the BLUE MOPAR regulator, about forty bucks, and if it still flickers, it ain't the regulator.

These are considered a performance item, and thus, have no warranty, but no warranty is needed.

Ok, mine do this too on the 91.5. Only does it with truck running, will not with engine off. And where is the regulator located?

I have a goofy looking silver tube a little bigger than a AA battery that hangs down under the dash and plugs into a modular plug with 3 prongs. WTF is that? My 90 doesn't have that anywhere I have found yet.
