I've got a 98 JRSC GSR.
I'm throwing 2 CELs after I connect my p28 ecu.
I'm pretty sure there's a problem with my conversion harness. When I plug in my stock ecu obd2a p72, I get no CEL's.

When I plug in my p28 (custom chip) I get CEL 20 and 41
When I plug in my tuner's p28 I get CEL 19 and 20

Where is the obd2a connection for the Heated Oxygen Sensor Heater? and where is this wire suppose to go on the obd1 connector??

 

From this image, It appears that the heater sensor is D13 and D14

This site shows that D14 is not used on OBD1

But what about D13?? D13 is missing from the list!

 

The obd2a D7 (PHO2S) is connected to C14 (P02)

The obd2a A6 (P02s) is connected to A6 (HO2D)

shouldn't

obd2a's D7 be connected to obd1 A6? and

obd2a's A6 be connected to C14
