Batboard

I'm looking for a place to tap ignition hot on a Dodge PU (2500 4x4). I usually use a timer instead but this user specifically wants his radios to switch by ignition (through proper relay of course).
thanks to all

Very useful link, thanks for posting it.
On Kens inquiry I believe many tap the FM radio B+ lead for ignition sense
as there are no cranking transient voltages on it.

dident even think of going for the radio. just make shure you dont get the constant power wire.
