Dear Ben Taber

Thank you for your inquiry.

We regret to hear that there is an issue with your TB70.
We have checked our data and found that we do not have the color code information for the GB4 product.

We have now prepared this information for you.


Although we are not familiar with the wiring system of the TB70,
we hope that the color code information for our Rosewell GB4 4P Shield product will be helpful to you in addressing the issue.

If you have any questions don't hesitate to let us know.

Best regards,
poul – Production manager
