[Camt149]

Hi an after a bit of help here!

I fitted some bucket seats, and stuipdly put the subframe over the top of the harness going to the yaw sensor resulting in esp, service light and abs light coming on, on dash.

I decided to cut the harness and rejoin it, in
however, now the lights are still on but now the speedo dosent work and the handbrake and engine light are now on also!!!!

any ideas??
