Tanxalot,

For your mystery blue wire, I have a thin red wire and thin black wire with a resistor on it running off my turret MG. There are 3 wires coming from the cannon, thin red, thin white, and a thin black to thick blue. (Not sure if this helps you)

Ok, I have followed your wiring diagrams and:

-gutted the main board
-removed the existing IR system (although I have not been able to find the IR emitter, is it in the cannon????)
-prepared the turret wiring for a new wiring block.
-wired the turret MG to the Hull MG.
-Removed the battery compartment and glued the battery hatch on.
-Removed volume switch and RC Crystal hatch that was glued shut (***!)
-Put filler in all the holes left in the underside.

Question:
I am mounting an RX-13 board inside the T-34. What colours are the positive and negative wires running off the motors?
