Having alarm issues with 2005 HIghlander 3.3.

Would like to know the locations for ECM and BCM. Also a schematic or wiring diagram would be handy. Actually just need the pin out for the units so gnd level can be checked.

Thanks,
John

New observation. I got the voltage up, turned switch on, then off/on 5 times. Clicking stopped but starter would not engage. Then I pushed the little red indicator on the left side of dash and it worked. I thought that was just an indicator but must be some type of reset too.

Please lessen my ignorance.
