I wanted to let everyone know that on Saturday my 1948 Willys CJ2A turned over.

I've never felt so good.

With that being said thank you everyone.

A recap: the above wiring diagrams are going to get you exactly what you need.

Keep in mind that if you are using a ballast resistor it's a simple fix... Just put the ballast between your ignition switch and your coil.

Your coil will more than most likely state of your need a ballast resistor or resistance wire on the front of it. For example my new coil says "use with external resistor".

If it doesn't say something like that - chances are it has an internal resistor.

It's there to reduce the voltage so that your points, which are in your distributor, don't get too much voltage - if they do it will shorten thier life greatly.

Also your coil ground through the distributor - so if you are trying to start an old jeep - you need to also make sure the points are good or else your coil won't even be able to send spark in the first place.

I'm extremely greatful for everyone's help.

Thank you.

I'm asking about Walcks wiring diagram. They have  (4) wires grouped together - (2) yellow with one black tracer, and (2) blue with one white tracer. I'm so confused about where these go. The tail lights and the brakes lights are the sam lights, right? And it also says "Connector at terminal block" for one of the the yellow with black tracer. I though there was only one terminal block - up front for the headlights? 

I'm not even sure if I've given enough info to get an answer. 
As always: thank you.

The yellows and blues are for the front turn signals. Walcks doesn't know what type of signals you might use, so they don't have a finished end.

If you have chosen to use turn signals, a 3-point terminal block is used in most cases. This is where the yellows all come together. Original terminal blocks had 2 terminals points. You didn't need more than 2 because the original 2A set up did not have turn signals.

This photo might help...

 Hawk - Stop a minute, blink your eyes, shake your head, now look at your picture.
 CJ2-A's use a three-post connector on the LF fender - one for the high beams, one for the low beams, and one for the park lights. The turn signal wires connect together with bullet connectors. In your picture, you can see the bullet connectors hiding behind the other wires. You also might want to get that extra nut out of there before it starts some mischief.   BW

I’m starting my wiring. I think I will follow your second diagram (with alterations for single wire alternator). How did your turn out?  Did you stick to that diagram?  Also I want to put in a fuse box. Where would that go in your diagram?
