Mark Sipe is the man!

Debbie mentioned my issue to Mark yesterday, and last evening he came by to help me with the bulkhead.

We cut out some sheet aluminum Mark had and bolted it between the seat support rods and the rear deck. It's not exactly a "firewall" as it's not sealed, but it's an additional layer of protection if my fuel pump or swirl can springs a leak.

I may try to go back over it with a rubber mallet, a drill, and some sheet-metal screws and really try to seal it up (Mark thinks this would work pretty well), but I've got a laundry list of other things to get done on the car before Saturday, so I'll only get to it if I have some spare time.

That said, does anyone know if the WRX's tach signal line is a 50% duty cycle square waveform, and what line I'd need to tap into at the ECU?
