put some new headers on car last nite took car for a drive just round block because i wrapped headers an i know they smoke abit when fresh on, got to end of road and my dashboard lights went out then 2 minutes after my headlights when onto full beam and wouldn't switch back, so went back home to find the headlights wont turn off only when ignition is off and rear lights are out

real brain twister so any feedback would be much appreciated cheers all

 

That sort of behaviour usually stems from a bad earth somewhere.

Have you disturbed anything while doing the headers?

 

just looked under car and wiring loom has burnt through
another job got to get car remapped after changing headers with car running funny on boost
