I want to install a bow thruster but need to know how to run it on a channel other than the main two I have a 4 channel spectrum any wiring ideas will be helpful .
Will I need a separate ESC unit or are there servos or switches to operate the unit.

It can be done a number of ways, for infinite control it will need an esc, however if you just want it 'full on' then using mini lever switches so they supply power to the bow thruster, these can be mounted at each side of the rudder servo or linkage. When you put the tx lever to maximum rudder the switches would supply power to the thruster. You can then 'blip' the tx lever to maximum and get power when required.

But as I said first, using an esc and seperate channel gives the best overall control. For wiring diagrams, check out the Action part of the Component Shop  website, there are wiring diagrams to follow. Alternatively, speak nicely to Inertia by pm and he might be able to give you a diagram.

Hello Rick (there can't be many boat modellers in Stoney Creek, Ontario)
 
Your P93 has been repaired and is on its way back to you (if it hasn't go there already).
You should first find out which channel on the receiver is controlled by the LH Tx stick side-to-side movement. You then connect a regular electronic speed controller to that channel and use it to control the bow-thruster, exactly like a main motor. Make sure, however, that you don't exceed the voltage for the bow thruster motor - many are only 7.2v. If you use the P93 as the ESC for the thruster then you can set it to Mode 2 (50%) which will allow you to run the 7.2v motor from a 12v supply - with full proportional control - from a main 12v battery.
As Brian has said, there are numerous wiring diagrams showing bow-thrusters here http://www.action-electronics.co.uk/wd.php
