alright so idk how a simple install could cause me trouble but i installed my interceptor gauge and connected the red power line to the pink boost gauge wire and was running both gauges but problem is when i turn my car off it runs for like 5 seconds while the key is turned off and the gauge doesn't go off. Then i take it off my port and it shuts off normal. idk what i'm doin wrong please help. thanks.

 

did you take off the jumper outta the interceptor?
