The oxford ones I bought come with the inline resistor, but I was looking to try and fit them without to minimise the wiring under & around the bolts for the rear end, but may look at seeing if they can be ustilised. Thanks again
thanks everyone for the responses, eventually fitted the oxford supplied balance resistors. I didnt want to fit these initally due to the amount of wiring around the tail attachment area, but got them all in and they are working. May well purchase the CF13 GL-02 relay as advised by Hubaxe as a back up if the balance relays do not last. thanks
