Yep, I tried wiggling the ign switch. I suppose tomorrow I'll run a wire to the green one. Already took the switch and lockplate compressor back, and I like that tool! By the green wire, I assume you're referring to the one next to the black one that we tested early on?
EDIT: Forgot to ask....Which fuse block would be best? Under dash or under hood? I know there's two posts on the side of the under hood one that some connectors are bolted on to. Think I could go from there?

Well, hooked the wire up directly to it, but still nada....My brother and I went through and removed all the un-necessary wiring (aftermarket fogs, water and oil gauges, scanner radio....) Basically just cleaned all the wiring up and I made sure there weren't any broken original wires.
Now my guages, warning lights. hazards and still turns don't work! The hazard only flashes the right side and I tried swapping flashers, but no change! What the actual frick!!?? I'm starting to really consider just replacing the entire vehicles wiring harnesses, front to back. Problem is, I don't know where to get it....
My brother had a thought of maybe the computer going bad, even though it runs just fine with no hiccups. I personally don't think it could be that, but I HAVE proven myself wrong many a time....

Fortunately, none of this crap runs through the computer. That said, a lot of the non-computer stuff is interconnected. The symptoms you're describing sound like a dodgy connection to the cluster. They're prone to this and it's possible that you inadvertently did something while installing your stereo. I would wait for others to support this theory before pulling the cluster.

Well, they were working fine right after I did swap it. I suppose I should mention I swapped in a different cluster with actual gauges instead of idiot lights. I don't know if it'd make a difference and I didn't see anything wrong with it when I pulled it.
All the circuitry on the back appears good, the warning lights ALL worked before all this started happening....Seems like once the turns went, everything started to go with it.

Step 7 tells what to do if no power at terminal L....http://www.jeep4x4center.com/knowledge-base/index.htm

Wasn't able to do anything today due to rain. I don't have a garage, so everything would be outside. It got pretty bad here for a while. Should be clear most of the day tomorrow, so I'll do as much as I can.

Just curious, but does the wire coming off terminal L stay the same color down to the flasher? And does it go into any bundles of wires?

It appears to run straight to flasher slot wire should run thru harness it says BK were going to assume that means Black. Is their current in either slot where turn flasher mounts in fuse panel with key in run or accessory position. You did confirm flasher relays are working by swapping them into hazard relay slot correct ?

Yeo, confirmed they work as they should. Cleaning up the accessory wiring the other day seems to have taken out my left side hazards. I tried following the black wire, but it goes into a couple bundles on the side under the dash that I'll have to take apart I suppose. I think I'm going to pull the entire dash off in the next couple days to have full access to everything. Seems logical to me....Move as much stuff out of the way as possible.
