1998 Chevy truck keyless entry

I have a '98 fullsize chevy truck that I would like to add keyless entry. The truck has power windows, locks and time delayed dome light. I have done some research and found where I think the module(receiver) goes. It looks like it replaces the dome light module under the dash. Is this the only thing needed to add this option? I know about the fob's and programming.

Also, will a receiver from any other vehicle work? I have tried to look for wiring diagrams, but most books dont cover this option, so its been impossible to compare. I had the dealer check the part number on what I needed and it was part # 16254970(receiver) and fob part#16245102. I also had him check an s-10 of the same year, but it had a different #'s. I was hoping to find these parts used and want to cover all the bases to make sure I get all I need to complete the project if I find a donor vehicle.

Thanks,
Bill

Bill,

Did you ever figure out how to add keyless to your '98? I have a '96 and want to do the same. Please let me know. My email is [email protected]
