Hey,
I just purchased mine off eBay. Power trunk release kit.
I am going to place the button to pop the trunk to the left of the steering column.
There a smiple kit but get rid of that annoying key factor. The key opening method is still functional if desired.
Just passing on the info.
There are none on eBay at the moment but keep checking in under "Challenger Trunk Release" as they pop up quite often.
Here's a photo of mine.
Cheers lads.
