Default LH2.4 CEL Output

Hey Guys

After performing a Kjet to LH2.4 conversion on my 83 242 I would like to have a way to illuminate a light if a fault code is thrown.

Looking at the pinouts from the ECU and ICU I see that ECU pin 22 and ICU pin 3 are the signal output from either module when a fault code is registered.

My question is does anyone know what output this signal is? Does in provide +12VDC when a code is thrown or does it switch to ground? Or something else?

Thanks in advance.
