When you are trying to replace an existing camera that does not use 4 pin aviation connectors you often have to make an adaptor up using your existing camera lead. This cable is one we have made up to give a 4 pin male connector one end and bare terminals the other. You can then slice this either onto the long extension lead that runs from front to back or take the safer option of splicing it on to your existing camera lead. Usually the cable colours match, although it is not uncommon to find other possibilities. Seeking our advice is often the best policy.
