Problem after wiring sidemarkers to blinkers

[M11's]

I wired my front side markers to blink with my blinkers. Guess with added lights couldn't send equal power to all four light so one blinker very bright and other very dim and one marker is dim other is bright. Also after wiring lights together my running or parking light option does not work also no running lights with the headlights.

Sounds like you may have wired these lights in series rather than parallel, meaning you are decreasing the voltage reaching each additional light down the chain. Let us know how you wired these together.

To wire correctly in parallel, you should split the 12V power wire between the lights rather than connect the ground wire from one bulb to the next 12V power wire and so on.

Followed this Technical Articles: Adrians13's diy sidemarker flashers (http://www.nicoclub.com/articles.php?id=201272). It connects blinker's green/yellow to sidemarker's 12V(red), sidemarker's black to other end of 12V(red).

What would it look to split the 12V?

This is absolutely wrong! Do not follow this write-up.

You should also write the mods and have this write-up removed. It is wrong.

You never connect two power sources together like what he did on the side marker. You're having problems with your lights due to current collision. This is why you're never supposed to do this.

Put everything back the original way.

If you want to do this I'll tell you how to do it correctly. Forget this ghetto stuff.

This is the correct way: Magic Blinkers Turn Signal Coverter (http://www.customdynamics.com/magic_blinkers.htm)

You can also build the same thing with a couple of standard relays.
