Every since we installed the switch to turn on/off my AEM TRU boost and UEGO gauges simultaniously I have been having issues where the In dash navi doesnt want to come on and also my scan gauge II thats plugged into the ODBII port doesnt want too either... itll come on sometimes but most times not...

Am i losing constant somewhere? drawing too much power? need a new alternator? Battery ect? Ive noticed since the turbo install it take slightly longer to crank as well...

This is a 2006 I shouldnt be having these kinds of issues haha... also have the viper 5900 installed if that helps? it acts a fool sometimes too!
