I have a 2001 F250 SuperDuty(canadian truck).
I converted my head light to 05-07 F250 one.
I am trying to put HID kit(high and low) in, but I get some problems.
With all original bulbs disconnect, and use the test light to check the ground, high beam power, and low beam power. It is showing the way should be. I only plug the HID harness on one side with all HID system plug in, , I check the other side bulb plug both high and low beam power have some kind of feedback. Like stay on low, high beam has feedback. Stay on high, low beam has feedback. I only get low beam and there is no high beam at all.
Please help me if anyone could figure it out.
