A31 RB20DET igniter wiring vs R32

[cefiro4]

Hope someone might be able to help me.  

So I have an A31 Cefiro (stock RB20DET) and bought a new coilpack harness that allows me to ditch the igniter by using different coilpacks with built igniters.  The problem that I've run into is that apparently I have a Series 1 Cefiro which annoyingly uses different plugs than R32 RB20DET. 

My question is, does the wiring on the A31 plug correspond with the R32 plug?  One minute with the razor altering the new harness plug and it will plug in, but I wasn't sure if the existing wiring would fire everything correctly.  I'm in the US so finding an R32 plug to swap my igniter harness plug to is a tricky proposition.

Any help is appreciated.

Not supposed to be different R32/A31

GTSBoy, if you look at that link it says that harness applies to late RB20DET models.  My car is a 1990, so was most likely built early enough to use the older plugs/igniter.

Hcr32typem , I had though of going that route and swapping connectors to later model ones but couldn't find if wiring matched up to later cars or not.

Having spoken to an Australian expert harness guy and sending photos back and forth and he tells me I have a igniter shared with the Z32 and he has the correct plugs so hopefully everything should be sorted because I'm going to have him make me a harness.

I swapped my ignitor out for a Z32 ignitor in my Skyline. Required repinning the harness' on both ends, or more accurately swapping the connectors side to side from the stock RB wiring. I'm sort of surprised the RB in the Cefiro is that different unless it's closer to the very early RB20 "redtops" from the R31 Skylines.

Hcr32typem, I always assumed that the wiring on Cefiros was the same as Skylines, so imagine my surprise when the plug turned out to be completely different.  Apparently from what I can determine, Series 1 Cefiros basically have silver top RB20s with redtop wiring.  Series 2+ are the same as a Skyline.  Makes no sense, but that's the hand you're dealt sometimes.

Maybe because they came out in 1988, Nissan was like "hmm we have a heap of redtop wiring harnesses lying around, stuff making new silvertop ones, use those instead!"
