Discussion and questions related to the course Practical Motorsport Wiring - Club Level
this has probably been covered so I do apologise.
We’ve been given a loom & link ecu out of another 3rz hilux going into another 3rz hilux my question is there’s about 9 wires that have been cut from something unknown to us & I just wanted to ask if they’re needed & if so where or what are they for is for aux
I’ve attached a picture of the pin outs they are from
once again sorry if his has been asked or covered previously
I think you should look at the ECU configuration and see what those inputs and outputs were configured to do. Then you will be able to decide if you need / want those features.
A5 is definitely needed, that is the main 12V supply to the ecu. As David suggests you will be best to connect to the ecu and look at the config to determine what those I/O's were used for. But likely they were chopped as they are all chassis stuff that was not part of the engine loom - fuel pump, fan, etc.
