So I was doing a bit of work on my car today, and cleared my codes the proper way with the green and black connectors. I follow the procedures again to enter active code check, and after a few minutes of driving with the green plugs connected, the following codes appear.
12 (Abnormal signal emitted from starter switch) and
43 (??? Google search says Throttle Switch)
I took a vid so you can see if I'm possibly misreading this

Car seems to run fine all the time - no fuel cut or any other wierdness. When warm, the boost gauge says -19 at idle. It's about -16 or so when cold. Boosts to ~6psi in the first couple gears, then right about 10psi for the last few gears, which is spot on for this ECU.
Here's the setup:
1991 SS
Factory 5mt
full EJ20G/ heads from a 96 WRX and intake manifold from a 90 Legacy/Liberty RS
EJ22t wiring harness
TD04 from a US WRX, 90* silicone bend to intake, coffee cup, stock airbox
JECS N/A MAF
440cc graytop injectors
WRX Slanty TMIC
EJ20G "3B" ecu, not chipped. This is from an early 90s WRX Wagon Automatic, lol
Phyrram's patch harness with an SVX igniter and 2 regular igniters. This ECU and patch harness has been successfully run on 3 SS's, and doesn't throw the same codes, on one, and has no codes on the other.
Everything else is connected in a 100% stock configuration for an early ej20g
Lastly, the code 12 goes away when come to a stop and let it idle for a minute or two. Won't come back till I reset the codes and go back into active check (and drive for a couple minutes - then both come back).
