On 2009 F90 , where's trim-gauge plug-in ?

[Wingless 32]

Almost done rigging .
Analog instruments + trim/tilt-switch work fine .
Trim-gauge does not respond . Needle allways in UP-position .

I can't locate where , on engine , to plug in the second of two off-white squarish four-lead contacts .
This particular one holding pink, orange, grey and black wires .
Please point me in the right direction

2005 and newer engine only have one off white colored square connector for gauge harness, if using the older gauge harness with two square connectors then requres an adapter but need to know exactly what gauges you are using, what are the part numbers on box the gauges came in?
