87 Thema 8v inj/ign wiring

[Roger Matthews]

Hi,
I am currently breaking a thema 8v turbo 87 vintage, I require the head, injection system, turbo and ignition.

The question is this, I have removed all the main mechanical items, and I am currently removing the wiring loom. The problem I am up against is, the loom seems to run from the injector rail, round the eng compartment to a point in the centre of the bulkhead, it seems to go through, but I cant trace it on the other side, it then comes back out of the bulkhead and carries on to the ecu and relay, what is on the interior side of the bulkhead side? I have by the way traced the loom on the ns of the car to the fusebox and disconnected it.
also is there a seperate ignition mudule?

any help would be appreciated,
Roger Matthews

Hi,
There are seperate ecus for injection (Bosch) and ignition(Weber). The ecu beside the battery is the Weber one and the Bosch on is at the extreme righthand side of the dashboard, tucked up behind it, along with the ABS controller (if fitted). The injection ecu is bigger than the ABS one. The Bosch wiring is a seperate loom which feeds through the centre of the bulkhead along with the ABS one. The Weber-Marelli wiring is part of the Lancia wiring and is difficult to remove (if not impossible). There seem to be several Weber ECUs in use and the wiring varies so be careful. Will send you a couple of diagrams that may help but will be Monday before I can scan them at work.

good luck! Leo
