That is actually correct!

 

The three prongs are part of the bulb "converter" (so to speak). Basically, the H1 bulb slots into this converter which in turn is secured to the back of the headlight by the spring clips.

 

So you actually have an H1 bulb in there, not H4 (H4 is a twin filament bulb and rather larger than H1 or H3).

All the best,

Thanks for the replies, i got as far as taking the plug off, saw 3 pins and stopped there lol

 

I will give it a go tomorrow

What is the difference between H3 and H3C? I just ordered an HID kit and asked for H3 bulbs. Will these fit in my 1990 Jap import? or am i going to be disappointed when they arrive?

Hi Paul, no you will be fine. The 2 spade connectors from your HID will plug directly to your existing bulb holder.

 

H3C has 2 prongs, H3 has one prong with a tail for the ground, the H3 hid kit has 2 spade connectors as stated above. Really easy and for now on one side, use some wire to ground the neg to the car body, to keep the HId's on when you use main beam. You can ground from the black wire from the ballast at the bulb holder

 

Then when you get time you can either do it properly at the relay or leave as it is. The only difference is that the HiD will flash on also when you flash your main beam, so as long as you dont flash too much you should be ok with the first mod.
