Ok guys I have this electrical conection on my TH400 I dont remember if anything was hooked up to it or not when I pulled the transmission & motor out. If it was I have no idea where the wire that unpluged from here went or goes, Can any one help me What goes plugged in here Is it a plug for a Transmission Oil Temperature Gauge? If so I'd like to put a Temperature Gauge in my Gauge Cluster. Anyone know the size of a gauge that would fit next to the Stock Oil Pressure Gauge the small hole Thanks Pablo.
