I have posted this on the SR forum because I'm installing the ignitor on a SR20, but they told me to ask you guys and FA.

I have an ignitor from a Q45. When I got the chip, it didn't come with any cut wires or anything, so I'm going to have to make a harness with some female spade connectors. That's not too big of a deal. If the Q45 chip came with wires, then I would have been able to use Q45 pinouts and convert it to my SR. Does anyone know what prongs go to what on the Q45 chip? I have SR20 pinouts so I don't really need any explanation on the harness side.

One side of the chip has 4 prongs and the other has 5. I have determined that the one with 4 prongs goes to the coilpacks, but I have no idea what prongs go to what.

On the side with the 5 prongs there is one "oddball" prong that is over to the side of the others. Would it be safe to say that this oddball is the power feed while the others are for the individual coils?

Here are 2 pics of what I'm talking about.
