    hey everyone I want to first apologize for this long post but have a few questions which may sound dumb but want to make sure before I finish up this install..

    I got the full AAW classic update kit for my 72 Camaro and in the middle of doing the engine/headlight wiring section of the kit.. there is some wires I wont need(horn,heater,ac,wipers) so ill tuck them away or just remove from the kit and for most part rest of the kit is straight forward...

    ALTERNATOR:
    After removing the old butchered engine harness I found that my alternator has a different connector then what AAW supplies. I will remove the connector and use the one that fits in the alternator

    since I have a 1 wire alternator I do not need to use this brown wire correct?

    STARTER:
    Continuing on with my butchered harness it has 2 of the same color wires going to the starter(which I believe somebody made both the same) one going to the BAT stud and the other was clipped onto this lil side terminal which I believe is the S terminal according to the diagram?

    http://i296.photobucket.com/albums/mm165/408maro1/20151010_164053-1_zpskfamrylz.jpg~original


    now the instructions state to add the 2 supplied cables in the kit to the BAT stud which seems easy enough, is the purple wire in the diagram going to the small S terminal circled in the previous picture? and the part in this pic I scribbled out I am not to use as this is used for a points ignition?

    VSS:
    I have a LT1 style T-56 and have a 2 wire VSS connector I'm going to plug into the trans.. now on the instructions it wants me to use 3 wires total.. any input on this?

    http://i296.photobucket.com/albums/mm165/408maro1/20151010_164555_zpsivzacfot.jpg~original

    IGNITION:
    I have a MSD 6AL box and I have the MSD blaster SS which has a -/+ on it. the blaster is connected to the 6AL, the AAW diagram wants me to plug these wires in somewhere for what I believe is tach and ignition? if so where should these go?

    http://i296.photobucket.com/albums/mm165/408maro1/20151010_163244-3_zpssyxcxidc.jpg~original

    and lastly I can wire the 12V IGN source from the MSD to a open 12V IGN on the fuse box?

    thank you for looking and appreciate any help.. just trying to finish this thing up :confused:

    I'm having a hard time comprehending what your question is? The big pictures on my phone is losing me. What's the problem?

    Do you have an internal or external regulator? Hei or points?

    The wiring for the alternator is pretty simple.

    Don't go re-inventing the wheel of splicing wires together, just follow those diagrams. I see you want to add wires?

    It might be helpful if you could resize your pictures--you might get more replies.

    I am not an electrical guru so you might want to verify some things, but I think I can add a little...
    1. Not sure about why you would have originally had three wires going to your alternator--maybe something to do with an external voltage regulator? A true one wire alternator literally has one wire, i.e the big one that is the output, it does not need "accessory" wire to be energized.
    2. Regarding the starter, I think that originally the positive battery cable went to the starter, and then ALL remaining circuits came off of this one positive connection. In other words, the starter terminal was being used as a distribution block of sorts. IMO this is kind of dumb. I would recommend taking a look at these articles: http://www.madelectrical.com/electrical-tech.shtml I think it is on there that I got the idea of making a distribution block on the firewall, fed by the alternator. Since yours is obviously a restomod, you might consider something like that. The purple wire is the one that energizes the starter during crank mode.
    3. For the VSS, I am thinking that the 3 wires are signal, positive and "reference" ground. Maybe your trans doesn't use a "reference ground"? (Just a guess)

    I don't know anything about the MSD box.

    thanks for the reply's guys and sorry I lost you there with the questions.

    I went back and cleaned it up a bit and added links to the pics since I cant figure out how to shrink them..

    if anyone can re read my first post and answer from that I would appreciate it..

    thank you all again

    I think what's confusing me is if you're using HEI and what starter your using, external volt reg?

    -what I'm tracking is there are only two connections to the starter. 1 is the Battery power/main power and 2. The ignition voltage wire (purple). The main power slips over the same stud on the seloinoid as the batt power and that wire travels to the alternator and is spliced to route into the fuse block as main power for the car.

    What connector do you need for the alternator? I have the painless kit and it cam with an assortment.

    The VSS doesn't need a 3rd wire. My electric auto meter gauge does need power to run, but the VSS directly does not.

    I think the MSD box is confusing you because I think you're focused on the points set-up. If you don't have points, no resisters, ballast wire etc. Scratch out all the "dotted" items branching off the 12v HEI wire including the yellow wire to the starter

    thank you for the reply..

    there was a external regulator attached to the corner of the driver side headlight area, not sure if it was even in use.. I know that the AAW kit eliminates that which I am sure is why they give a specific wire in the kit for it if needed.

    for the alternator it may have came in the bag if not I am sure I can go to orielys and get a replacement for it. it is just a different looking connector then what's given on the supplied wire

    got it on the VSS now, thank you

    I think I finally got it figured out on the MSD aswell.. for the most part I think I got it locked down now.. just got to figure out my Dakota digital once all this engine comp is done

    Someone could have upgraded the alternator in the past. The kit like my painless facilitates both depending on what you have. I asked about the connector because I may have if and will not be using it.

    AAW makes amazing kits. I've used them on numerous cars and trucks. If you have any questions, call them.....they will walk you through anything step by step while you're looking at what you're doing.
