I just finished this project and thought some details might come in handy for someone.
For the keyless entry system, I used a Bulldog Security KE1702-ENG-CL, which I got from Amazon for $42. I chose this one because their webpage (
www.bulldogsecurity.com) actually had wiring information for a milano. And believe it or not, it was correct! The power lock module is located above the fuse panel, behind that little glove box to the left of the steering wheel. I just wired up the keyless entry box according to the color codes on the Bulldog webpage, and everything worked the first time.
For the power trunk release, I first bought a cheapie $15 solenoid kit. It didn't have enough power to pop the latch, so then I found the much more powerful Spal SIL40K solenoid. I got it from
www.a1electric.com for $45. It fits nicely in a recess under the trunk carpet between the latch and the left side light assembly. It has plenty of power, but you need to run a 12 gauge wire. I connected a new wire to a spare unfused lug on the back of the fuse panel (look for the 10gauge red wires), added an inline fuse and relay and ran the wire under the carpet back to the trunk.
Anyway it was a pretty easy project and now my wife gets to pretend she has a new car!
