Just purchased '03 extended cab work truck with manual windows and found some cheap electric window doors... Replaced and hooked them up and thought it would be a 'snap' to add fuse, etc.. but,.. I have no power at all, only thing working is the speakers ,,, could not locate where I would add fuse, relay, etc. and electrical trouble-shooting is my weakness! Has anyone ever done swap and if so, what else do I need to take off 'donor' truck and what other steps are needed to get windows working... do not care too much about getting central locking system working as long as I can lock and unlock doors with outside key or just lock/unlock buttons.... Thanks for any ideas/help... if there's a thread already here, I could not locate it.... O.
