I am trying to find out as much as possable adout  A omega 2.2 dti engine wiring as ill be fitting it into a classic car!  The engine mountings and sump i would get round.
but what about the wiring could it be done.

is the engine wiring loom separate to main car ?
alarm?
what would be the basic wiring needed from the omega?

any help at all would be great

Engine wiring loom will be pluggable into car loom by battery as with most Vauxhalls.

it's quite dificult to make out what you need from your post - is English your first language ?

anyway, the engine wiring must be transferred completely, together with the code-reading whatsit around the ignition switch. From memory, the Frontera Haynes manual has a 2.2DTi wiring diagram, which you should copy and blow up. You'll thenbe able to replicate a loom for your car, and prioritise the feeds that you need.

At start-up, the engine ECU waits for a "handshake" signal to come from the key reader before it'll allow the engine to start. No code = no starty

id have to use the omega key and ignition.
i cant do away with the code-reading.
what about the alarm how would get around this.

no issues with the alarm, it's not connected to the immobiliser

do the wires from the code-reading around the ignition switch go straght to the engine ecu?

yes, I think so.

but I need to check it on hte diagram first.

(thanks for the help )dose anyone have wiring diagrams for the engine etc
