ECU PINOUT DATABASE

Post by Koukster »

I would like for a moderator to place this as a STICKY or in the TECINFO section. This is very helpful information. This site has the ecu pinouts for many different cars, as well as OBDII, OBD1 and pre OBD 240sx's.

The KA pinouts are incomplete. The following are the three connections for the CONSULT I/II interface:

ECU Pin7 - Grb/Blk - RX
ECU Pin14 - Grn/Why - CLK
ECU Pin15 - Grn - TX

Factory service manual FTW. :wink:

3: to dropping resistor to NPN collector
8: EGR Temp Sensor
9: condensor fan !EN
11: AC condensor !EN
12: A/T

This one should be pretty accurate I went threw the 91 wiring diagram, I did find a few in inaccuracys from other pinouts, cant remember which ones but this is pretty much straight out the 91 FSM.
