this is a conventional cab. thanks for the feedback i will check behind kickpanel on pass side and frame rail. thanks I read post from other ask.com and was told drivers side behind steering column (NOT)
I would think it would be on the inside panel and it could be shared with another circuit. It might be under the hood because it's on a relay. Look by the steering column on the firewall. It might be in there in that panel.
Next time start your own thread and your answers won't get buried and others with similar problems can search the thread out easier.
