The bus bar is whats behind the plastic in the i/p (instrument panel) fuse box if give one side of the fuse power. What he’s saying is take the fuse out and stick the tester in the both sides to see if the connection is just worn or burnt from a arc try scraping the metal a little bit see if you can make contact

I/P U/P we all P  ;D Yes Instrument Panel Fuse box (the one when you open the drivers door near the gauges)

That fuse in the i/p fuse block is fed from the underhood pdc 40A Maxi fuse I/P 2. If this fuse is good you need to trace this circuit as you have an open circuit. The first place I would look after that is Connector C200B and D. C200B is (18 cavities) Forward lamp to IP harness, between the left kick panel and the steering column and C200D is (48 cavities) Part of the IP harness, between the left kick panel and the steering column.

Well this is turning out to be a pita, there are 2-40A I/P fuses so I just checked both. And guess what, yep both good. So now on to check the next part you suggested. Thanks to everyone for the advice and help. But did I mention I'm really starting to not like this car.

LOL - Just think, when you fix it you'll feel great! Find the connector and check the connection. Look at cavity B4 and the wire should be red. Check it for B+ on both sides of the connector.

If I'm looking at it right it appears the headlights on the same circuit and they work fine the head light switch will also turn them on. It has the automatic type lights that come on with the key. and the dash lights do not work. I'm gonna print those and tackle it again tomorrow. Thank you for yur help' I will let you know how it goes.

Ok I found what you suggested and your right, no power coming from that wire. I guess next is to figure out why. Everything is wrapped tight nothing has ever been hacked into and I cant see anything that would appear to have moisture.

So on either side of the connector no B+? Then the problem is from the maxifuse at the power distribution center under the hood to the connector. I would unbolt the PDC and check for chafed, mouse chewed wires etc

Yea thats kinda what I was leaning toward but just wasn't in the mood to mess with it today. So instead I played with my truck it seems it always gets put on the back burner and I needed to relax and releve stress. So thats what I did. lol. I made an electric fan shroud a few months ago for it had it bent out of aluminum and polished it. Its just been laying around the garage so I did it tonight instead. When I get things how I want it I will put some pics up of it. But it came out sweet. Dual fans with a polished shroud. BLING!!! Vile, thank you for all your help I will let you know how it goes.

Ok, so I finally got in the mood to get this thing done. After all the tracking it was so simple. The wire you had me tracing was corroded right under the under hood fuse block. A cut, snip and new end put in the fuse block. All is good. Thanks to every one for the help.
