Wiring in late 70's 100 amp alternator into 69 Chrysler

I have a bone stock 400 engine from a 78 Charger that I want to drop into my 69 Chrysler until I rebuild the original engine. It has one of those giant 100 amp alternators on it. It has four wires: a giant ground that attaches to the intake manifold, an equally giant wire that is cut off which I think is the battery wire, and two smaller wires that were also cut off that were on a plug that attaches to twin blade connectors on the alternator.

How would I wire this into my electrical system? I already bypassed my ammeter following the instructions from MAD electrical (here's the link:
http://www.madelectrical.com/electricaltech/amp-gauges.shtml). So I guess I could run the giant battery wire to the post on the starter relay. I don't know what to do with the other two wires.

I searched the tech archives and didn't come up with anything, and I will dive into the wiring diagrams if I have to, but I just wanted to see if anybody else had already done this.

Also, if it helps, the ignition is already converted to electronic, and I replaced the voltage regulator with a transistorized stock replacement, no rewiring necessary.

I run one of those in a '70 Challenger. The core engine is a 400 from a '78 Cordoba.

The brackets should bolt up and belt alignment should match the late 60's/early 70's AC setup.

Electrically, the ground wire goes to a good engine ground... manifold or head are best. The big output wire should be replaced with new 6 guage wire running to the fender relay or directly to the battery. Solder a short length of 10 guage fusible link into the 6 guage charge wire for short protection. The 10 guage fusible link is available at an auto electrical shop.

The two smaller terminals connect to the standard 70 and later dual field regulator setup. I belive there is a diagram in the archives for converting a single field car to the dual field setup. Most parts stores will have everything you need.

Besides being a bit heavy, this alternator works great. Lots of idle output. It is the only practical "high amp" option I know of for BB cars with AC.

Compared to the stock small case alternator, the 100 A unit is higher and hangs out farther. On my car (70 challenger) I moved the receiver/dryer back an inch or so to clear the alternator. I also had to extend the cooling neck about 1 1/2" to get the stock style top radiator hose to clear the belts to a Sanden air conditioning compressor.

I'll try to post a pic as well.

will need to consider a higher upper radiator hose for belts clearence

I think he addressed that ...
