MS-ing an automatic

OK - so I've got the MS '99-'00 and my tuner is currently installing it. Question is - do I have to do a parallel install to the factory ecu or not? There are only 2 wires from the factory ecu to the transmission control module and can't find what the values are... if only 2 wires, say +12 and signal, then there's not much reason for parallelling anything... just needing info as what those 2 wires are value-wise. Pic attached fore reference... excuse the MS ignorance - or ignorance in general
