Seems most likely to be coincidence, but it's possible that the new 
brain is drawing excess current for some reason. I never thought 
about it before, but there's no fuse on that circuit. I have a meter 
that can clamp around a wire and measure the DC current. If you were 
here it would be interesting to measure yours and compare it with 

I've never measured this current on any car. I'll try to do this, and 
report the result.

If the new brain has changed the idle, as Keith suggested, that's a 
possible cause, but it would make me wonder why this happened. I 
wouldn't expect this, so it makes me wonder what was done during that 
previous intrusion.
