it has 2 wires in the pigtail. I was told on allpar it is externally regulated as well. But that still doesn't solve why the alternator is not charging I'm still waiting for flagship ship one to "work" on why the pcm they sent me didn't work. Guess ima need to get a refund from them.andnfind somewhere else that can program the pcm to the vin so it works in the car. If this keep up. Thanks for the input.

 

Requested a refund now searching for a known good place that sells and programs pcms.

 

I have never been impressed by Flagship Look into SOLOPCM and Computerexchange.com
Are you missing the ground control at the alternator or the power supply at the connector?
