Blinker issues

So let me see if I understand the problem...
- when you turn on your lights, the left turn indicator in the dash also lights up?
- if you then turn on your left turn signal, all of the running lights flash (side markers, tail lights, dash illumination)?
Does it only happen with the left signal or does the right signal do the same thing?
Have you done any modifications or repairs (replaced sockets, installed LED bulbs, etc.)?
Did anything unusual happen just before this problem started (fuse blew, ran through deep puddle, etc.)?
Do you have any electrical diagnostic tools like a multi-meter or at least a test light?
It sounds like you have a short between your turn signal circuit and your parking/running light circuit, but we'll need more information in order to determine where to start looking.
Yes with lights on left indicator is light up an yes blinks all lights an cluster illumination.
It's only the left signal light that flashing all the lights.
No aftermarket bulbs iv replaced the left front bulb an socket an the very out side small rear tail light bulb. This issue just appeared out of the blue I noticed bulb was out one day.
Investigation lead to burnt connecter on passanger front that's all the bad wiring iv been able to find was passanger front connector was toasted.

The first is that you've got the three wires of the new front socket connected incorrectly. The factory colors are black for ground, brown for parking lights, and blue for turn signals and DRLs. Unfortunately, aftermarket replacement sockets don't come with matching colors and sometimes even do stupid things like using black for something other than ground. If the socket didn't come with a connection diagram or a wire color listing then I would remove it and bench test connections until you get the correct combination then reinstall.
The other possibility is that you may have installed an incorrect bulb. Installing a 3156 bulb or a 3157CK bulb (used mostly by Toyota) in place of a standard 3157 bulb will cause similar cross circuit connections. This is less likely than the socket wiring but it is possible.
The nice thing is that both situations are fairly easy to correct without costing a lot of time or money.
And I can't remember off top my head Wich bulbs I got but I have noticed wiring to connector gets hot after some time or driving or running the lights.
Wich brand of socket would you recommend for better chance working correctly.
The socket I have O'Rileys cheap one all the wires on socket were black.
I Trusted the guy at counter I'm going to pick up the right socket from Napa that's listed an wire coded to match the car.
It's more expensive but I'd rather have the right socket out the gate.
I'll try this if still same issue happens I'll keep you updated thanks for all the information.

First, confirm that it is a 3157 socket with three wires - a 3156 signal socket with two wires will cause exactly the symptoms you describe. Then, if you have a multimeter, I can show you how to test which wire is which in the socket. If you don't have a meter or are unfamiliar with testing continuity then buy yourself a different 3157 socket that doesn't have three black wires - each wire should be a different color - and that labels the wires or has a diagram on the package.
If you have a meter, you can check your socket like this...
Notice how the contacts on the right side are connected top and bottom? That's the ground circuit. On the right side, the bottom contact is the dim filament for the parking lights and the top contact is the bright filament for the turn signals and DRLs. Now you could test every contact to match the continuity with each wire until you labeled all three but you really only have to match the ground. Check which of the three wires has continuity to the connected ground contacts on the right side in the image. It will be one of the outer wires. Mark it as ground. The middle wire will be the parking light power (brown wire in factory harness) and the remaining outer wire will be turn signals and DRL (factory blue wire).

I tried swap waring in the old/new connector I'd previously installed like you suggested an I swapped the two wires my brown wire is running to center of connector.
Now that swapped the outside 2 I'm have tail lights blow fuse an the only drl working are front drl/blinkers.
I'm begining to believe my cheap socket is to blame I'm take brake from it I'll go out later an put the new higher quality socket in try again
Now blinkers work as they should an no blown fuses drl work on front but what all is supposed to be lite with drl?
Because I have no markers lite up or taillights.
When the headlight switch is in the P position (parking lights), the front lights will still be bright and the tail lights and side markers will be on. When the headlight switch is in the ON position, the headlights will open and turn on, the front lights will switch to the dim running light mode, and the tail lights and side markers will be on.
The drl had being only front my parking light had melted the socket an jumped to the drl prong in the socket I had all lights on from start.
I guess once fixed wiring was to much for the tail light fuse blew them new socket on everything back to normal thanks again for all advice an info.
