Guys,
As some of you may know I'm building two Cobra replicas with LS400's providing engines and gearboxes.
Having equipped myself with the excellent wiring diagrams available through this site and buoyed up by the sage advice and encouragement of Lextreme members I went forth into the freezing cold garage this evening to see if I can make sense of the diagrams and start to wire one of the beauties up in the completed chassis in which it sits.
However it quickly became apparent that the two engines I have ( one 1990 and the other 1993) have different plug and pin arrangements on their respective ECU's both of which in turn show no relation to the wiring diagrams I already have.
The 1990 ECU has sockets with two rows of pins, three sockets grouped together and then one seperate socket, whilst the 1993 ECU has smaller square sockets, all four in one row with four rows of pins in each socket. I did take some piccies but I need to shrink the file size.
The 90 ECU pin configueration is 26 16 22 26, whilst the 93 ECU has 34 22 16 28. Has anyone got the wiring diagrams that relate to the ECU's I have? If so copies of them would come in very useful indeed.
Also if I ask my Lexus dealer quoting the ECU part and serial number will they be able to give me the wiring diagram for the exact cars my engine and boxes came from? ( I do doubt this, bearing in mind they were unable to date the engines from the engine number).
I have the engine and gearbox loom complete as it comes through the bulkhead with the plugs on it. I do not however have the fourth plug ( 26 pin in the 90 ECU and 28 pin in the 93 ECU) that was fitted from the cabin side of the vehicle. Can anyone tell me what inputs I need to put into this plug ( I'm planning on getting said plug from a friendly Lexus breakers ).
I bought the engines and gearboxes complete and unsplit from the breakers but they were already out of the vehicles so I hope I got most of whats needed to run the ECU's barring the fourth plug.
Any help gratefully received....I'm now off to get a hot toddy as my gas heater in the garage broke today as well......
Cheers,
Tony
