H4 conversion harness?
I got a 200mm rectangular hella h4 kit but no adaptor harnesses. Do I need one or can they be hardwired up with any basic h4 harness? Basically cut the old pig tail off and find what goes where and solder on a h4 harness?
What are you guys doing for this mod. I doubt it's something I'd reverse or take off if selling

Oh wow! Wasn't expecting that at all. When I did my dodge stealth twin turbo it needed an adaptor harness. I didn't feel like tearing into the vette without the right parts. Thanks for the quick answer!
I'll be running the hella 60/55 that came with the kit until they blow, still a great difference in light output vs sealed beam

don't touch the bulb with your fingers.

Some years ago when I had a '92 'vert, I bought the Hella H4 conversion kit. I can't remember for sure if the kit included a harness but all I had to do was to install H4 bulbs in the housings and plug the factory connector into the bulb.
IIRC, the purpose of the conversion harness had something to do with how the two power and ground tabs were positioned on the bulb. Some aftermarket bulbs (especially the Xenon style aftermarket bulbs) had the tabs in different positions compared to a stock lamp. So the harness simply connected the bulb tabs to the correct position for the factory harness.
The bulbs I used were a Xenon style and were something like 90W for both high and low beams. Never had a problem with the stock wiring, never blew a fuse. But I don't think it would be a good idea to go with a much higher wattage than that.
