Wiring diagram for splicing P66 transducer into a 12 pin harness

[c1steve]

I am installing a TZT3 12F and will be using a P66 triducer for the time being. Original MFD was a Raymarine C120.
I plan on splicing into the Furuno 10-12 pin adapter cable.
Airmar PN: 31-468-1-01
Rev. 3
Cust. part #E66054

If someone could post the wiring color codes that Furuno uses in the 10-12 pin cable, that would help. The Airmar cable has:
White, brown,
Green, red, blue, black,
plus shield and bare ground.

We do not recommend modification of the adaptor cable. The recommended method would be to attach a 10 pin pigtail cable to the transducer (normally color for color because it is Airmar) and then plug the transducer into the TZT3 10 pin to 12 pin adaptor. This ensures it can be moved over and used for a TZTXL using its supplied adaptor (which is different) later. The needed 10 pin pigtail is https://www.furunousa.com/en/products/air-033-333 or you could make it easy and pick up a new P66 with Furuno 10 pin.

It isn't something Furuno folks would be willing to assist with. It is a bit like helping someone disable the airbags on their car, if you know what I mean. If done incorrectly you have a good chance of damage to the unit as well.
