EDIS Coil Connectors

[trakkies]

I'm moving the EDIS coils on my RV8 to a better position, and now is the time to make a decent job of the EDIS loom. I've ordered up cable to match the colours at the EDIS8 unit, but would like to use new terminals at the coil connectors. I have a suitable crimping tool.

I can find complete new connectors at a price, but being a parsimonious person ;-) would like to buy just the terminals, as they come apart quite easily. Does anyone know what they actually are so I can check with UK electronics suppliers? US places seem to charge a fortune for postage to the UK when such things could just go by letter post.

The connector on the EDIS8 unit defeated attempts to disassemble it, so I'll have to put up with splices there, I suppose.

Making up my new EDIS8 loom, I came across an abnormality in the MegaManual diagram. I couldn't understand why it said the A coil was on the right of the unit (plug to the bottom) when my coils are marked 1&6 on the left hand one. I assume Ford would use No1 cylinder as the benchmark and number the coils from there.

I have the bits of an original Ford loom, and the wiring colours give a clue. The MegaManual has reversed the connections to the coil plugs. Not that it matters if you're starting from fresh, but confused me. So I've re-drawn the diagram giving the original Ford wiring colours:-

With the 36-1 wheel correctly phased
pin 8 spark A
pin9 spark B
pin 11 spark C
pin 12 spark D
and the manual is correct.
You will now have to establish the firing order ( be sure also to understand cylinder numbering) on your particular engine.
The firing order established, use the coil towers associated with spark A for the first and fifth, spark B coil towers for second and sixth, spark C for third and seventh and spark D for fourth and eigth.

Since the coils are identical you could use any coil for any pair of cylinders - assuming you swapped the input connections too. I just wondered why the MegaManual swapped the connections to each pair of coils, rather than sticking to the factory way. This just adds to confusion. Or does with me. ;-)
