Yup! Don't tell but I think it was an errant fine touch sent it into the interweb thingy before of started finger typing. But I won through in the end if you look back now.
I try to take a look the battery today but didn't see anything extra connect to the battery terminal except those from the factory. Do more tracing on that plug harness today and found and extra grey plug that branch off from the plug harness. Talk to a friend and compare to the block heater picture from Toyota Canada webpage and he think that grey plug is for the block heater.
