[Icom] Toyota firewall

[Chris BONDE]

I was not too explicit on what I meant by the following.

"I plan on using the power plugs, ie, the extra cigarette lighter plugs to 
run it.  I would like to remove the ash tray and use that area to put the 
face plate in.  Has anyone tried this?"

I would use the power plug not the cigarette lighter.  As I donot smoke, 
the ash tray with cigarette lighter is expendible.  The lid therefor a good 
thing to hide a faceplate, or, a small device.  The power plug is marked 
max 12V / 120W.  I think that it would handle a 50w TRx.
