Engine wiring harness question

I got a new engine wiring harness and installed it partially, ran into some questions on the connections forward of the alternator, what do the connections go to after the circular washer looking connector that goes to the alternator post?  The harness came from year one, I know that some will go to the washer reservoir and the horns/horn relay, but not sure which goes where.  After doing some research I found that I'm missing the horn relay, must have removed it years ago and its long lost now, so will have to get another.  I thought one of them was supposed to attach to the alternator spade connector but none are wide enough to fit the one attached to the alternator.  As far as I know both of the horns still worked fine before I unhooked them. 

There is a single green just above the alternator connection,  not sure what it connects to.  Long enough to reach the spade connector to the alternator, but isn't wide enough to fit on the spade.  Also long enough to reach the AC connector but this is the wrong harness for an AC power lead. 

Single Brown, positioned about where the washer tank is, could be for the washer pump but the pump has a T shaped double connector under it.

Single Black and White wire, may go to the horn relay, but also could go to the washer pump. 

T shaped double connector, one lead is a purple wire, the other connector has two green singles coming off the plug with a single spade connector on the end of each. 

69 RT/SE Y3 cream yellow w/tan vinyl top and black r/t stripe. non matching 440/375, 3:23, Column shift auto w/buddy seat, tan interior, am/fm w/fr to back fade, Now wears 17" magnum 500 rims and Nitto tires. Fresh repaint, new interior, new wheels and tires.

I'm at the office right now, otherwise I would double check things on the car to confirm.  Apologies for that.

When I did mine two years back I used the following two diagrams to find the connectors I could not sort out.

Those are for a 69 Charger.  In case you have a different car you should be able to find your respective diagrams here --> http://www.mymopar.com/index.php?pid=27

If those don't help you I will try to take a peak at mine later tonight or tomorrow.

May not be a direct answer but will hopefully help!

peek at it when you can, I appreciate it, reading schematics like that is why I decided electronics wasn't going to be my career field.  Does look like a green wire is supposed to attach to the alternator which may explain that one, may have to get a different spade connector for the alternator to use it.  This is the engine harness that starts at the bulkhead connector,  crosses the firewall connecting the oil pressure, voltage regulator, ballast connector, then runs up the valve cover to the alternator and on to the washer tank and horns.  The harness that goes to the headlights is still the original harness for now, may swap that one out later.

Will have to say that reading flow charts for software development isn't a far cry from reading electrical diagrams.
