where to find metra wires?

so i go and buy a metra 70-7552 Radio Wiring Harness for Nissan 07-Up and it's short 2 wires for the steering wheel controls. there's no extra wires i can use on the harness. i don't want to hack the factory wiring to install the steering wheel controls, but according to Metra (when i asked if extra wires were available) "No there is not. You will need to tap into the factory wires for the ASWC to be installed" my first reaction was "ur f--kin business model is based on people not wanting to hack their factory wiring, yet ur telling me to hack my factory wiring?" anywho, where can i get a couple of extra of these wires? maybe someone on here pulled them out of an install they've done and have them laying around? maybe mouser or radioshack has them?

Which steering wheel control interface are you useing?

metra ASWC.

I would just T-Tap the wire(s) the SWC needs behind the factory plug.

Buy another 70-7552 for your nissan .  Remove two wires with pins attached out of the new harness and relocate them to the original harness. 

soldering directly to factory wiring is more of a hackjob than finding 2 pins to stuff in my metra harness.... i didn't think there were gonna be no extra pins, but worse yet that the only answer to "where to get more wires from" is buy another $15 harness.... i was honestly hoping that someone here ran or worked in a shop and had a few extra wires they extracted out of of a harness that didn't need them..... i didn't want to have to touch the factory harness to do this install....

Neither method is a hack job of any kind and implying such is an insult to the majority of professionals on the market. For the record in MOST applications the wires for the steering wheel control module are not in the standard deck install harness. If your so concerned with not touching the factory harness than spend the extra 15 and buy your second harness to acquire your pins, or you can just do WHAT THE INDUSTRY STANDARD is and solder the damn module in.double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer
