1st of all, the horn relay needs to stay,,,,,(if you still got the stock wiring), the feed wire from the Positive battery cable at the starter solenoid goes to one of the screws on the horn relay,,,,,make it 10 gauge at least and put a fusible link on it so When, not IF, the wiring shorts out and catches the van on fire, if you got a REAL 1 wire alternator, the output goes to another screw on the relay,,,,,,Pink, on the input side of that connector next to the drivers seat is Ignition,,,,,,,the output of that connector is the 6 volt ballast resistor wire which you dont need anymore,,,,,,Purple is start to the solenoid, Red goes to the relay screw,it feeds the whole van,,,Black and Green go to the horn relay,,,,Dark green is temp sender,,, Dark blue is oil sender,,,,,,Brown is idiot light,,,,,,that voltage regulator goes away,,,,,,that brown idiot light wire goes to #4 on the regulator,,,,,,but you are way better off just hooking a voltmeter to the fusebox and throwing away the regulator and those 4 wires hooked to it,,,,,,

what size fusible link?(is a fusible link ,just a smaller wire or is it special made?)would a mega fuse be a better option than the horn relay?
if I don't use a one wire ,I would use an 80"s style ,I just need to know what wire to use for the exciter wire?
whats the best way to hook up a volt meter?

the horn relay has 2 circuits in it,,,,,,,those screws on it are basically a junction block, and they also power the relay so when you press the horn button, the black wire turns on the relay and the power from those wires on the screws, goes out the green wire to blow the horn,,,,,its just the way the van is set up,,,,,you can make it any way you want it,,,,,,,you need a 14 gauge fusible link connected to the Positive battery cable on the starter solenoid, so if there is an electrical short, it melts and disconnects the battery from the van,,,,,,IF you are using a 3rd Gen Alternator,,,,you know,,,,the best in the World,,,,,,people even put them on their Fords and Dodges, you take that brown idiot light wire, hook it to #1,,,,connect #2 to the output terminal and run a 10 gauge to the screws,,,,,you want the voltmeter connected to a terminal on the fuse box that turns on with the key,,,,,,that oil/temp light is useless,,,,,it comes on after your engine is knocking or head gasket is blown,,,,,and you need to figure out which it is,,,,,
