Power trunk upgrade?

[scahartman]

Anyone tried to upgrade their Signature model to a power trunk open/close like on the ultimate? I'm trying to see if it's possible and the cost involved.

I haven't heard of this, but I would be very interested to know what the cost might be as well. For me this is the one option that is sort of a deal killer for me when comparing the signature with the ultimate.

If I could get my hands on a shop manual we could get a parts list put together a go from there. Any source suggestions?
