O.K. this will probably get moved to the electrical but here it goes. I have my pyro hooked up, with the power coming from a fuse in the panel ( can't remember which one). When I turn my KC lights on which are wired straight to the battery, the needle on the pyro jumps around and does funky things. What gives? It also does the same type of thing if I hold both window buttons at the same time after they have already reached the top or bottom.

Any thoughts.

Thanks, Jacob

Check to make sure you have a good ground on the pyro.

I don't think its the ground, it just seems as though it is taking too much juice from one place, and that the electrical system has priorities on what is the most important thing that should continue working so for example instead of stopping the windows from going up and down when both buttons are held at the same time it takes juice from the pyro, or something along those lines if you understand what I am saying.

Make sure all of your connections are good. Take them apart and do them again. Not sure how you made your connections, but make sure all strands of the wire are under the lugs, terminals, etc., if you used sta-cons, make absolutely sure that all crimps are good.
