Adding Guid to a Lookup field

Question

I have written the below function :

function openConnectionForm() {
    "use strict";
    var parameters = {};
    var id = Xrm.Page.data.entity.getId();
    id = id.substr(1);
    id = id.slice(0,-1);
    parameters["record1id"] = id;
    alert(id);
        var entityName = "connection";
        var windowOptions = {
            openInNewWindow: true
        };
        Xrm.Utility.openEntityForm(entityName, null, parameters, windowOptions);

}

I have a ribbon button "Connect". When I click that button, I want to open Connections form and I want to pre populate the field "record1id" with the guid of the record on which I click the ribbon button.

The form is opening on clicking the ribbon button. But, the field "record1id" is not populated as expected. Some garbage guid is added.

What am I doing wrong?

Update :

I have changed the code to :

var id = Xrm.Page.data.entity.getId();
var name = Xrm.Page.getAttribute("fullname").getValue();
alert(id);
alert(name);

var parameters = {};
parameters["record1id"] = id;
parameters["record1idname"] = name;


var entityName = "connection";
var windowOptions = {
    openInNewWindow: true
};
alert("Done");
Xrm.Utility.openEntityForm(entityName, null, parameters, windowOptions);
alert("Form Opened");

The form is opening.

But, when I click on the contact, I get this :

It looks like you may need to pass three pieces to the parameter. See here.

Example (untested)

parameters["record1id"] = [{
    "entityType": "contact",
    "id": id,
    "name": "John Smith"
}]

Working Code I've used

var systemUserObject = [{
    "entityType": "SystemUser"
    , "id": this.currentUser.SystemUserId.Value.id
    , "name": this.currentUser.LastName.Value + ", " + this.currentUser.FirstName.Value
}];

Xrm.Page.getAttribute("ccseq_leaduserid").setValue(systemUserObject);
