Hi.

I 've a 1984 Land Rover on which I am swapping an engine with a 3.9 liter petrol from a donor car. I got the engine from a mechanic. Not sure from which car it came. I have a problem starting it. I have been told that I need a new ECU and the wiring harness. I have not been able to trace the kind of ECU it has. I attach the picture. I'll appreciate if anyone could help me get the ECU and wiring harness as the rover is just sitting otherwise.

Also, if I cannot find the exact ECU, can I put another ECU and the matching harness. Would be a good recommended one.

Thanks.
