I'm pretty sure the Putco has mechanical relays. They make a loud click when activating the lights or high beams

 

The fog lights (or DRLs on some vehicles) need a ground wire added to function with that harness. I had to do it to my Camaro (same lighting system) because nothing worked right due to the fogs.

Legally, vehicles can't have fogs and highbeams active at the same time. I'm not sure why, but the law requires highs to interrupt fogs.

 

In addition to this, DRLs commonly use a lower voltage than normal operating lights and most relays are meant for a 12V on the control-side. I believe XJ DRLs run around 3 or 4V. Fed into a 12V relay you get a whole lotta clicking and buzzing, which is bad.

I think the fog/highbeam thing has to do with total light output and possibly aiming. At any rate, requirements for this change on jurisdiction. Up here in igloo country new vehicle requirements country-wide are like the above, but provincial requirements mention nothing of the sort. DRLs aren't even actually required. However if you live in an area with bi- or annual inspections they might go over these things.

 

The laws on that are similar to catalytic converters. While some locales don't have laws or may not require them, the federal government does.

For anyone interested, DRLs are Daytime Running Lights. They're growing in popularity in the States and have been used in Europe for quite some time. They're different from the marker lights that most XJs have or newer vehicles' automatic headlights in that they are always on whenever the car is running (or, sometimes, when the car is in a forward gear). The intent is to improve visibility in low-light conditions.

They generally (from what I've seen) operate on the same sort of circuit as a factory fog light.

 

A new to me brake booster because the old one looked like this

 

Oh they're actually required down there? Up here it's literally a condition of being approved for sale as a "new car", like certain crash rating or fuel economy. DRLs are not required in any shape or form after that, rather unlike emissions systems. It's kinda silly actually.

 

Sorry, that was poorly worded on my part. The cutoff system preventing fog lights and highbeams from both being illuminated is required. DRLs aren't in any way, though some automakers choose to make them standard. No studies since '95 have provided persuasive evidence that they help.

 

I would have to say they help in heavy rain, snow, bad weather conditions. It rly ticks me off to see people driving down the road during a monsoon with no lights on because they 'can see just fine.' I mean come on people, they aren't for you, they're for others to be able to see you... its law that headlights have to be on if you are using your wipers but with DRL's, you don't have to worry with manually turning them on everytime you run into a rain cloud. It's always older civics or camrys that don't have 'em. lol

 

All done with the hood vents.

 

Don't know why you put them there but if the bad spots on the clearcoat of my hood are any indication of where the most heat is located you got'em in the right spot.

 

Removed my rear seat from my DD today, actually yesterday. Not really by choice. More to follow.

residential hvac vents?

 

that sucks. anyone hurt?

 

No, no one was hurt. The Jeep is literally a heep now. We had to drive home 1.5 hrs, so I had to cut a hole in the windscreen to see. I can't believe how it held up. Jeeps are awesome. Definitely what I want my children to drive!!! Will become parts for my project.

Yeah ill have to find out how well they work.
Yeah haha its metal with slots
