Valet 561T ch 2 output

Does any one know if this unit has a trunk relaase output. on the box it comes in is says so. and in the manural in the quick refrence guide is mention, but in the main harness is says not used, and in the descriptions of the wires tere is nothign listed. any one have a clue. also in the program menu feature # 7,12,13,14 is says no function. i do see this a lot in program section in others manurals. is there somethign that can be change. why bother put it in the manural if tere is no function.

there should be a RED / white that is 2nd channel output (200 ma negitive output)......is there a AUX on the key fab....Where theres is a wire there's a way.

its is listed as only in the quick guide, but there was no RED / white wire in the harness. but it dotn say how it is used. i no longer have it so i cant play around with it to see how to use it.
