Heavy Duty Headlight Harness and 4 Hi

[96C1500]

I think I see a problem with this circuit. Wouldn't the Low Stock connector supply 12V to the New Hi Connector when the low beams are on?

Unless the stock switch switches the ground and not the power or both it does look like it will. Has anyone tried this layout, I wonder?

When the stock high beam connector turns on it also turns on the low. I went over it a few times and it looks fine to me. Also the same diagram I'm using on multiple vehicles. Unless I'm missing.

I also usually choose to use the 3 relay method

But when the low beams are on, the brown wire from the stock connector is providing 12v to purple wire that goes to the high bulb by being connected at the relay trigger terminal, so not only is the low beam relay being triggered, it would also be lighting the high beam.

Hey purefection I want one of these HD harnesses with 4 HI. I want to run dual HID's so I want it straight from the battery. I'm in Ontario, Canada. Have any around?

Thanks, Casey

I run 4hi with a pair of 35w and a pair of 55w hids and I got my mod from painless wiring from jc Whitney possibly jegs might have one

What's the main difference with the heavy duty harness??
Gauge ,relay,??

I'm not actually making these to sell, I just don't have the time. I see what you're saying on that diagram. I think in another thread it was fixed. I'll try and find it. I prefer the three relay method anyway.

The only difference is guage. You can buy the eBay relay harnesses for like 8 bucks and it's the same thing. I get the same voltage at the ends of a eBay harness as I do at the ends of a HD harness. The relays on the eBay ones are **** though so I would recommend buying your own and just putting it in the harness. It just plugs in the socket anyway.

I think if I can get a good line on materials I will start making these. As an Electrician I can get some pretty good deals on all of this.

Did you ever start making these?

The exact one I'm using on all of my canyon lights. Not using the relay that came with it, but you could. Nothing wrong with it. I just had some really expensive relays left over.

Negative. I don't have the time. I work 24 days on 4 days off right now on 14 hour days.

If anyone wants to start making them feel free to contact me for information. I can walk you through making one pretty easily.

I thought of using a single relay but something tells me that 3 separate would be better and it's also more cost effective. If someone wanted a double or single relay setup I could do it though.

Drew a new one up. Little easier to follow and shows it going 1 wire back to the auxiliary power post near driver door.

I think this second diagram is incorrect. It looks like it will light the highs when the lows are on. And the power for the high is being pulled from the original low +.

The first 3 relay diagram looks fine.

I have never done this but planning to build my own harness since they can't be bought anymore.

I could be wrong...
