Many people are happy with 12v 40a Switch Relay Fuse 6 6ft Wiring Harness For 72 300w Led Work Light Bar Discount after buy them and I expect you will be too. Check the removed fuse; replace it if it is blown. This compact circuit is very useful and. Turn the dome light switch to the "OFF" position. Thanks, will definitely try the light bulb test. ive replaced ign switch. Been going through it and fixing all the small issues. First i checked the tow/haul switch in the shift lever and thought it was that, so I replaced it, and it still blew fuses.
