I recently bought a new headlight/parklight harness after installing it i tried my indicators and and hazard lights but they didn't work. I changed the fuse for my hazard lights and when i tried the hazards after about four blinks it blew the fuse again. For the time that it did work it only blinked on the dash and none of the exterior lights blinked. so if anyone could help me it would be muchly appreciated.

 

Unplug the front harnees and try again. If the fuse still blows the trouble is else where. If it does blow, plug the harness back in and unplug or remove all the bulbs on the front. Try it again, if the fuse still blows you have a hot wire shorted to ground or a bad harness. If it doesn't blow plug the bulbs back in one at a time until the fuse blows. At that point you have isolated your problem.
