You cannot swap 1&4 with 2&3 on the coil module or else you will be firing on intake and power as opposed to compression and exhaust, unless you were to swap the timing signals on the primary. Suppose you could make up an in-between connector to do this but could be quite ‘messy’.

I’ll re ask Avguy’s question, how did you test the coil to determine it was bad?
Did they all have the same failure?
Likely you primary side is OK , and you are experiencing failures on the high tension secondary.
You will need to test the resistance of the defunct coil pack and narrow it down from there. If all your measurements have the correct impedance then you may be having an insulation breakdown on the coil itself, which can be caused ‘as you indicated’ by heat but as well a bad plug cable or plug itself.
Remember , once the energy is created in the secondary it will find a path , if the plug or wire doesn’t provide this then something else will get compromised and it could just be a diminishing spark on your 2&3 secondary.

hope that makes sense,
Cheers
