The problem with Andre 3000's loom is this, at pin 20 of the c101 connector runs a red wire with a white trace, this wire comes from the main efi relay so it has a 12v positive feed on it when the ignition is switched on, on the fuse box side of the c101 connector at pin 20 is a brown wire, brown = earth so when the ignition is switched on smoke and destruction happens due to a short circuit to ground. So obviously the looms supplied cannot be a matched pair, Either a correct loom is needed or the right information to correct this loom to do the job.
If anyone has the right info/parts/experience feel free to get typing.
**edit**
Problem now solved, the burnt wire from the efi main relay is to power up the abs, this engine loom has now been fitted to a car without abs which has an earth wire instead of the wire to power up the abs control unit. The wire in question will be removed as it's not required.
