Hi all iv used a 1uz engine to power my r33 skyline. Iv used the wiring guide on here and had the engine running for a few secs then it cuts out. After checking the donor car I can see the ecu is immobilised.
I still have the donor car but can't find a wiring pin out for the immobiliser box to wire it in.
here's the ecu number of the immobilised one
89661-50310, Immo box is 89780-50010 and it is from a 1996 UK ls400 ucf20
Iv also got a ecu part no 89661-50160 fr9m a 1993 ucf10 ls400 which doesn't have an immobiliser, when I plug this in the main relay doesn't get switched on so doesn't run.if I swap the igt wires around and bridge the relay it fires for a few seconds then logs fault code 15 and cuts out.
Can anyone help to get either of the ecus to work for me?
