Towbar wiring assistance

[Micheloaks]

After purchasing the towbar last year with harness kit had end of year run around with cpl of installers including  .... I just fitted the Stenhof tow bar last weekend to my 159 SW and wanting to use it next cpl days finishing the install a must . All auto elects booked for weeks in Canberra.

CPL questions with the supplied harness.

Can I use the rear 12V socket as a permanent live  to wire the 10amp 'fused' black box? Preferable to running the wire all the way to battery.

I'm assuming the sealed black box supplied with the harness is in reality some relay?

I've also spliced the supplied harness into the rear lights and now have disabled both left and right brake lights . As per above first post , should I be extending the supplied wires which are both short and thin, so can wire into both  lights ?

Any assistance appreciated

Thx in advance
