I mounted my ECU & fusebox under passenger footwell. Harness go thru grommet near fuel filter down to ECU & fusebox. Then it is routed from fusebox down thru top end of tunnel (should have gone a bit higher with this as I was thinking you might see it form inside of engine bay!!) then along underside of tunnel & up into boot area etc. Hope this is of help.
