Wait to start with timer How to perform wait to start on diesel vehicles without attaching to the wait to start indicator wire
Some diesel vehicles have sensitive wires that make interfacing with the WAIT TO START indicator difficult. The 528T Pulse Timer Relay is a simple bypass for any diesel vehicles in which access to the WAIT TO START wire is difficult.
Adjust the 528T Pulse Timer Relay to stay active for approximately 5 to 10 seconds longer than the WAIT TO START indicator stays on.
