Replacement NB Coilpack

Hi all,
I purchased a replacement 3-wire coil pack for a 1998 NB MX5. Problem I'm seeing is that the stock coil pack cylinder order is 4-1-3-2, however, on the replacement coil pack it's 3-2-1-4 --- is this going to be a problem? Or am I able to trust that the replacement is wired in such a way that the firing order is safe?
Thanks!

Its says in the background MX5 Mania- why not ask them- they should certainly know.

I would, but I imagine they are closed today, and perhaps for the Christmas shutdown period too... I'm going overseas on Tuesday and am hoping to have this replaced before then :/

Found this from here
https://groups.google.com/forum/#!topic ... AqSd-H5MhM :
Each sparkplug in a Miata sparks twice per cycle. This means you can switch
the wires of two cooperative cylinders (1+4 and 2+3 as I believe). However,
you are _NOT_ changing the order. It stays 1342. Switching 1 and 4 on a 1342
will not result in a 2341 ignition; it stays 1342.

Confirmed... replaced the coil pack with the new item; no problems with the plug order at all...
