digital tach engine connection

[chweiss]

Purchased a 2002 F115ltr and connecting a digital tach 6y5-8350T-82. I have harness 68F-82553 which has two plastic connectors at both ends. On the engine I located the one connector which I believe is the trim sending connection beside the main harness but cannot locate the second (for oil pressure?). Where should I look? The electrical diagram on the parts search shows one beside the main harness so I must be looking in the wrong location

Help would be appreciated

Thanks

It is usually behind the main harness coupler in that holder.
