This is usually an easy task, however, we have no access to schematics, therefore, making the job a little harder. Even if you do not have a need for a shift light this post will also also show how to access switched power, this is needed for other aftermarket accessories.
It is always best to wire to a terminal block and not directly to a device, it makes it easier to trouble shoot and terminate. I decided to use a fuse block as my terminal block because I intend to use switched power for more than one device. The fuse block will allow me to isolate/protect separate circuits.
We first need to locate switched power. When you analyze the PDC there are some ommissions and errors between the fuse location schedule in the owners manual and the actual layout. There are not many options available. I used a "Add-A-Circuit" (AAC), which uses an existing fuse socket. It basically gives you an additioanl circuit, The key is to find a switched circuit, in the picture below the vertical part of the AAC plugs into the fourth slot of that five slot group. In my SRT the fifth slot is open because that is for the adjustable shocks.
The picture below shows the terminal block (fuse block) and the ground block that i added on top of the drivers footwell. I had to remove the cowl cover to mount these, when you put the cowl cover on, the blocks cannot be seen. To ground the lower bar I ran a wire to the the aluminum casting that the windshield wipers are mounted on, this is factory tied to the firewall and the frame.
The red arrow denotes where the cable for the shift light enters the cabin. The green wire is routed to the #7 coil pack. It is the easiest coil to work with. You first have to remove the drivers side engine cover, it is removed by lifting the cover about 1/2" thenpulling the cover out the front side.
There are two wires entering the coil pack. You have to tap into the solid colored wire. It looks like a gold color conductor. For information sake I put a scope on the gold wire and it had 400 volt pulses driving the coil.
The Raptor shift light is Velcro mounted to the top of the column. If you install a Raptor, the Cylinders X Pulses = 1. The new viper must not have the waste spark like the Gen2, that program value was a 2.
