Ever since I had my A'pexi turbo timer installed, everytime I shut the car off a weird yellow "4W" light on the left side of the guage cluster blinks twice and then goes off. I have never seen this light before at all, it just started doing it ever since the timer was installed. Any guess as to why it would do that?

 

that light is for the ABS system, why it comes on due to your turbo timer is weird

 

Damn electrical gremlins....
