Parking lights and 2 dash lits all that are working HELP!!

*pics added* Parking lights and 2 dash lits all that are working HELP!!

So my tuck (89 chevy) sat for a couple of years while I was in poor health, i'v been putting it back together when i did the only lights on the truck that are working are the 2 parking lights up front with sidemarkers and 2 lights on the dash. Plus all the lights on the HVAC unit. i put LED lights in the gauges while the truck was down but i have quadruple checked those and they all seem right even had a guy who does LED conversions check it he traced it to maybe being in the headlight switch. I'v tried 3 different switches will the same result.
I'v also checked all the grounds I could find and they seem good. the one on the fuel door was loose but I fixed it and still no luck. I'v also checked all the fuses, everything is good.

So could it be the harness that goes to the headlight? the LED's and we just are missing something? or something else?

I suck at electrical please help!!!

u check all the sockets? They get mucked up with corrosion real easy. Do a 4-hi mod, clean out yer sockets, check the main harness plug at the firewall,(to the right of the steering column)and see what happens from there.

starting to wonder if it's the cluster. are the head & tail lights on the same circuit?

 

[shelbyt.67]

No. Its gotta be a bad terminal,socket type a thing. U check those sockets? Check the terminals at the back of the fuse block and the distro. Check the ground at the front to the battery/frame and ground at the rear frame.

the gauge light sockets in the clusters are whats acting like they might be bad. I spent several hours checking sockets

 

[shelbyt.67]

The cluster sockets may be bad but they wouldn't affect the chassis lites. The chassis lite problem has got to be a bad ground or power. U may have to run thru the harness to see whats goin on. Maybe mice chewed up yr wiring? Have u checked all yer relays?

I did some digging and found this wrapped up in electrical tape and tucked under the battery tray

it's about 2 feet long and runs off the positive cable on the battery I dont see where it connects to but I'm sure it has something to do with my problem. I dont see on any digrams where it goes but it looks like a ground of some sort to me
