When faced with a dead regulator, I had no clue where the "long" wire went. After some judicious tugging, I discovered it went the B+ post. Problem one was that it was nicely incorporated into the wiring harness at the factory and you could not pull it back from the regulator end due to the large terminal lug on the end. With the battery disconnected, I clipped the end off and pulled it out of the harness. The rest was not too bad. I mounted the regulator and fussed around with the connections making sure they were secure and Ty wrapped as close to what the factory had done as possible. I then encased the long lead in a length of split wrap and laid it in along side the existing harness. I attached it to the B+ post and the Ty wrapped it to the harness for support. This all happened at 1,400 miles and I now have 5,600 miles on it. The only side effect is that I know always drive with voltmeter selected...:)
