Idiot Lights to Gauges Questions

[Delo69]

Ok I've been to GMC Pauls Tips page and I've read the several forums but I'm still confused and have questions.

I have a internal reg alternator. I have a red wire from the alternator, a red wire from the junction box and one that comes from the cab and I am going to join them.

1. I moved all the wires per GMC Pauls site and have the blue and brown left. Do I tape them off? I thought the blue wire is the alt wire?

2. Reading the GMC Paul Tips for the conversion the #1 and #12 spot I need to run wires with inline fuses..#1 need a wire to be tapped into the red wire coming off the alternator...the #12 need a wire from junction box to the #12 spot.. Is that correct? Cause to me if I do that its like running the #1 and #12 to the battery..and then ontop of that how do you wire them into the gauge plugs without the clips?

I'm jonesing to get my truck put together and running so she can get new tires and the wife and I can go for a ride.
