Guys, I am needing a bit of help with my current scale set up. I have a BRXL, HH 45t, Airtronics winch servo with Hayok control module, spektrum receiver, a hightec ? (410 oz) at 7.4 high current steering servo. I will be running all of this on 2200 3s 30c lipo's. This is were I need help. How do you recomment I wire my system??? My winch control is rated at 6.0 v and my steering does 300 oz at 6v but does 400+ at 7.4 v.

Use a y harness to plug wire the BEC directly to the servo. I have mine setup like this:

and it works perfectly. No need to pull the red wire from your ESC.

I have my 2.2 comp truck setup that way. Just make note of which wires have been removed from that harness (one red and one black on the Rx side and one white on the BEC side) and you should be good to go. You can set the BEC to whatever voltage you wish and the Rx and ESC will still function normally.

You will still need power to the receiver and winch. It looks like the y harness does not supply power to the receiver with only a signal wire to receiver. If you use this setup you could send 7.4v to your servo but still have to get 6 volts to your winch and rec. If it is what it appears to be.

Yep, that's why I said not to pull the red wire from his ESC.

The receiver gets power input from the ESC just like it would without the BEC and servo system using the y harness.

I have never applied that much voltage to a receiver, I guess it's will work.

benoj is correct. The ESC puts out the full voltage to the motor(s), but the Rx is limited to somewhere around 6V.
