HKS F-CON iS Piggyback ECU + Harness
 

Pristine condition, absolutely nothing wrong with the unit.
Priced fairly decently, so don't expect any lowball offers to fly.

$550 for ECU
$75 for wiring harness
$600 for both

Took it out of my '05 WRX STi as I decided to have a manual tune done on the stock ECU. Was in the car for ~3 years. Vehicle itself never had any electrical issues, or accidents etc.

Also have wiring harness for above STi. Can sell you one or the other, or both.

I don't know what other ECU's this thing will work for, but I'd imagine they're OK for a few years of the STi.
