I recently installed the Putco wiring harness relay and after installing it my high beams dont work. When I hold the stalk or turn them on, my headlights just turn off. Once I turn the high beams off or release the stalk my headlights come back on.

I know it's not the headlights because for the first couple weeks I still had the sealed beams until my Rampage H4's arrived and the same thing happens with them. The harness is definitely doing it's job, but does anyone know why this is happening?

I don't think I installed it wrong, its really just plug n' play. It isnt that big of a deal since I never use them but it would be nice to have working just in case.

 

Hmm several possibilities here. First check your headlamp fuses. All of them. The one that activates the relay may be blown. Second swap the relays. It may be just a bad relay. double check all connections, might be a loose connection. After this you will have to do some troubleshooting. It would help if you had a test light or better yet a multi meter. But check the easy stuff first.

 

If you have factory fog lights there's an extra step you have to take. I have not done this upgrade yet but read a couple threads on it. You have to run the fogs to a pin on the relay I believe.

 

What year is your XJ?

If it is 97+, try removing the DRL relay in the engine-bay fuse box. I had to remove mine for some reason, as my Bi-Xenon projector high-beam relay would stay ON all the time because the line actually has a very low voltage even when not activated.

 

X2 on this I had to do the same in order for them to work properly!
