after market headunit
 

I cant seem to find any link for the wiring that i should install in order to use my dash buttons.

any links where i could find it guys?

try the electronics forum. i think there is a harness for this

gotta go to modifry.com and get the harness.

i tried modifry, but my pioneer headunit is not listed there.. what can i do?

No head unit works directly with the dash buttons.

Modifry makes a device that translate the signal from the dash into a signal that some head units can understand (IR or hardwired).

Failing that you can buy a PAC SWI-X that learns the commands from the head units remote and does a conversion from the dash signals.

if your headunit supports a remote control, either IR or wired, the odds
are good that Modifry's DCI will work for you. if your headunit doesn't,
nothing will work for you.
what model Pioneer headunit do you have?
