keyless entry

[Speedy]

Hello all,
now I will install in my car Seville STS 96 europe version a receiverbox for remote keyless entry.
My question: Does any place exist with the wiring harness for the original box ?
Is the receiver box in USA version a seperate box ?
Needs any other electronic a modification or software update ?

thanks, Sascha

The connectors should be burried somewhere around the location of the box, GM prewires one harness for all the cars. To add options just pull down the harness.
