            These radios have a delay built into their turn- on time.  A push      

            button “ON” or "OFF-ON" switch must be installed in the blue 

            bypass wire to be activated after the radio completely boots up.  

            The bypass has already pulsed before the radio has booted and 

            won’t bypass the parking brake without this switch. 

               Any questions contact us 

We offer two types of switches to remedy this problem.  A mini toggle "ON-OFF-ON" which is featured in this listing and a mini push button type normally closed, when pushed opens the circuit, then when released closes.  Which ever one prefers.  Mini button type found at Ebay item # 127183031703
