One of the things I wanted to do is add an electric trunk release; I have had them on my Challengers for years however I have never tried to do one on a Cuda. There are several guys on this forum who have done this which I looked at carefully, but I finally dug into it yesterday. It is far easier than expected and took about 30 min. What you need is the following;
1. a OEM (old school) mopar electric trunk latch
2. a cuda trunk latch
3. some type of grinding device
4. basic hand tools
What you are going to do is disassemble the cuda latch (you are after the release cam which is the part that the rod from the key/lock attaches to via a plate). This is accomplished by grinding off the heads of 2 rivets and also 2 small square tangs. Once you do that, you remove the release cam.
Then you remove the cover of the electric latch by removing the 2 push locks off the pins. Once that is off, you remove the release cam.
You will need to contour the Cuda latch release cam to a similar profile as the one from the electric latch to give it enough room to move. This is not an "exact" deal, you can profile the Cuda one little by little until you are scared or satisfied..
Put the newly profiled Cuda release cam into the electric latch; you will need to open up the hole in the plastic cover just a little but to allow the cam to rotate, this also require the underside of the bolt (boss) to be sanded down a little bit as well to provide clearance. This is not hard to do, just apply a little elbow grease and sand paper or a file or a dremel. Just don't get too froggy on it and remove a bunch or open the hole too big (it is really close from the beginning).
grease everything up, put the cover back on, replace the push locks (any well stocked hardware store or even the HELP section of your local auto parts store should have them) if they broke coming off.
bolt into place and adjust (Disclaimer, I have not adjusted mine yet, but I am confident it will work).
The latch grounds to the body and only needs a power line to work.
