Si 12 install help with plug ID thanks VetteVette
Just installed my 100 amp si12 and everything is great and working. I decided to clean up and retape the wire loom while I was at it. When I finally got the tape off I noticed this plug that was taped up with everything. I can't seem to locate it on my wiring diagram. Any help would be great. I would like to get it hooked back up, it's there for a reason lol. Thanks everyone the Colors to the plug look like black and blue.
On a side note if anyone is thinking about upgrading there alternator to the SI 12 amazon has AC Delco 100amp for 60 dollars. Great reviews. Only bad thing is apparently AC Delco now has there stuff made in China like everyone one. So let's see if it lasts lol. Thanks VetteVette for an awesome post on the conversion I found. Everything went smooth and your way of doing it was way better and cleaner than the others. |

Running and blinker for the front of the grill or bumper--other side will be dark blue and black.
looks like you may need a tad shorter belt |

The alternator I took out was in the same position on that bracket (maxed out) I didn't notice any issues, I will run it for a bit and see how it goes. The tension feels good but it is maxed put on the bracket. Hopefully it will be OK. Thanks for the response and taking the time. |

Re: Si 12 install help with plug ID thanks VetteVette
The plug with contacts shaped like a T plugs into your radiator support. You should have a mating plug in a hole there that passes through the signal to your front parking light/turn signal.
The plug with the light bulb in it fits in the side marker light. I had an alternator pulley that looks very similar to that one in your picture. When the belt is thick and stands above the groove a little bit like that, it will cause the belt to wear down and become thinner, and I found it causes the belt to lose strength and traction and will chirp and squeal. I bought a deep groove pulley from an eBay seller and that solved the problem. I thought you might like to know. I can't tell for sure from your picture, but it looks from here like the belt is thicker than the groove is deep/wide. Here is the one I bought. https://www.ebay.com/itm/201649847243 And here is the discussion about the belts and my pulley swap. http://www.67-72chevytrucks.com/vboa...d.php?t=797722 |

Thank you for the kudos. I can't take credit for the conversion but I will take credit for modifying it and putting it up on the forum for all my fellow truck owners to use..
There are hundreds of members like my self that love sharing their knowledge with everyone. It's what makes this forum the best on the internet.
