Hello,
I have a 1998 P38 2.5l.
Where can I find a pin allocation for the tachometer? I need the pins for the oil pressure lamp, parking brake lamp and the abs lamp specifically.
Thanks

In the ETM section in RAVE. But you won't find dedicated pins for various lamps, signals from the sensors go to the BeCM which sends a data stream to the instrument cluster which then displays whatever lamp it is being told to display.

pin 7 of C114 is labelled as "low oil pressure".
pin 10 of C112 is labelled as "ABS warning lamp/message".
pin 2 of C112 is labelled as "Parking brake on".
Hope it helps ...

Those are at the BeCM rather than at the instrument cluster. Pin 7 of C114 is grounded when no oil pressure and the switch is open circuit when pressure is there but will probably show a bias voltage from the BeCM if checked with a meter. Although pin 10 of C112 comes from the ABS ECU to the BeCM, pin 11 of C112 is the only connection between those two listed under the warnings section of the ETM. What conditions you are likely to find is anyone's guess, it might be pulled high under a fault condition, it might be pulled low or it could be data. On a 98, pin 17 on C626 is grounded when the handbrake is on.
