96 Buick Regal pink wire

I am wiring up a Stinger SR200 solinoid. Stinger says to wire to a true ignition source.  The car audio manager at the store I work at says to tap into the pink ignition wire. Well, I crawled under the dash and found 4 pink wires comming from the steering column. Two were fat and two were smaller.  Which one is it?

Thanks for the quick reply. I decided to whip out my multimeter and find which one has 12 volts with the key on. Found it. Then I decided find which wire to use to wardwire my head unit to swithed 12volts under the center console. It appeared to be the yellow one. I then looked for the power antenna wire. It appeared to be the dark green wire. Wired everything up. Stereo worked fine except for the power antenna did not work. Turned off stereo and removed keys from ignition. Ran temporary wire to antenna to see if the connection was bad. Stereo did not come on this time. Disconnected stereo wire harness from deck. Noticed the lights were a bit low so I decided to start the car to get a guick charge and POOF!!, a cloud of smoke came from just behind the engine side of the firewall at about center position.

I can not find what I fried. All fuses are good. I cannot find any fuseable links anywhere. None of the wiring appears to be melted, nor can I find anything that smells fried. Now my car just goes, click, click, click....everytime I turn the key.  I still get a switched 12v to the wire I ran for the SR200.

I am open to suggestions as to where to look.

Thanks for the support.

I checked all the fuses and found them all to be good. I still have 12volts everywhere, both switched and constant. I also placed a screwdriver between the contacts of my starter to see if it would spark or even try to start and did not get a response. I am assuming I may have fried the starter. I have not checked any fuseable links because I cannot find any.

The next morning I remembered I had forgotten to take my charger off the battery before I tried to start it.. I had it on a 10 amp charge. Could that be a reason I smoked something?
