I am using a set of the projector housings I got from Ebay, they came with H4 bulbs for all 4 housings, the lows plugged right in, my high beams are a 2 blade connector, any ideas?

H4 bulbs are typically not used in the high beam position. The only other thing I can add is that the high beams use a single filament bulb, which the H4 is not.

You need to find a single filament bulb that will fit your housing. But I doubt you'll find one if the housing is made for an H4 bulb.

Single filament bulbs I'm familiar with are the H1 and H3, have a different "base" than an H4.

You can use the H4 as a high beam if you figure out which terminals are gound and the high filament. Make a couple of jumper wires from your existing terminal to the bulb. You'll have one unused terminal on the bulb. Can't say for sure if the beam pattern will be good though. There's another thread here that you started that explains this.

H4 headlights also require the connectors to be repinned because the Hi/Low/Ground are rotated 1 pin to the left as you look at the back of the light.

For my highs (inner lights), I wired the two together so that I used both filaments as a high beam light, this also requires a slightly larger fuse because you have twice the current draw. My Hi/Low beams (outer pair) I repinned and left alone, but of course I built and installed a kit similar to the one in the tech articles.

You got a diagram for that repin, cause my low beams are just plugged right in and they work fine, but if it's not right then I need to fix it, also I bought an H4 plug like the one for my low beams to I can try and get this to work right

Check the links in my previous post. Those came from the tech articles on the home page.

So which one is for the high beam the top one or middle one? I cant read the text it's all choppy

Al Hasse

Why would the text be all choppy?? It's an image and posted in the tech article as an image.

The top diagram shows the back of an H4 bulb. Hi/Low, doesn't matter, for your high beams, just use the 2 opposite pins and you'll be fine.

The middle diagram shows the back of a sealed beam light (like stock) for the Hi/Lo, or outside pair of lights.
