before i blow more £££'s how in-depth does it go? ll ecu/ecm pinouts included?
many thanx

Its simply a wiring diag. Pin numbers are included, but not connector pinouts.
Title: ecu pin 29 (immobilser) for omega 2.5 td 1999

sorted the pinout for the ecu  :o

next issue is the immobiliser !! pin 29 on the ecu, does anyone know what happens on pin 29 when the engine is running ? grounded or 5v+ or 12v+ ? or data?

what circuits in the ecu are controlled by the imobiliser line? starter? fuel liftpump? fuel distributor pump?

1999 TD will expect a code from immobiliser ECU - seeing as the immobiliser and engine ecu are paired, I'd say this is not going to be a simple hi/lo, but some kind of data transfer.

Do you have access to the immobiliser ECU, if so, just connect it up with a valid transponder chip glued to the top of it ;)

Immobiliser needs to be programmed to ecu.  Not sure if this is a 'once only' option, or can be done with 2nd hand parts  :-/
