Thanks Martin, I think I've read the same before, but for several reasons I believe it actually attaches to the rail.
I do have plans that appear to show them connected to the rear rocket rail mount. However it isn't clear where and the rear mount, on the plans, is not the same as the actual rail. The rockets stand off from the wing a ways, because of the rails, the pig tails may not reach the wing? Nowhere, on plans or drawings, or indeed on the model, are there any indication of sockets in the wing. The fact that the rails were not a Permanent fixture would suggest a connection through the rail?
As you can see I'm pretty convinced that the pigtails did attach to the rails, my dilema is where, exactly?
