LED hedlamp install - ZR-1 Net Registry Forums

XfireZ51 · 11-15-2018

I recently bought a set of OSRAM LED headlamps. In process of installing them, and I notice that on the headlamp buckets for my ZR, there are only 2 adjusters,
One vertical, one horizontal. However, the FSM shows 3. But the bucket has provision for only 2 so it appears that it is not a case of missing parts or anything like that. It looks stock.

Dom,

Did you opt for LOAD RESISTORS, or clip/ground the FOG LIGHT RELAY?

Where did you end up getting the headlights?

I’m going to connect a separate ground. The horn ground is very close to the fogs.

Wayne,

I got these off Amazon.Mistakenly, I ended up w another set also. Once I get these hooked up and tested I may sell the other set.

Paul,

Just realized I can’t do it that way. Hate idea of clipping wires.

Take a look at the way brother Yun (secondchance) solved this issue with a relay terminal jumper.
He laid hands on my Z when when I switched over to GE LEDs as couple years back and all is well with the fog lamps.

Did mine as well but recall we cut a wire and then grounded it. All is well with fog lights.

First two Zs - mine and dregeguy's - I located fog light ground wire (light green, I think), cut and grounded. Third Z, Phil's, I pulled the fog light relay, bent the ground leg, soldered about 8-10" long wire and grounded it. Both methods worked fine. The latter, relay leg mod, avoided cutting any factory wiring.

Yun,

Are u saying you grounded the fog lamp at the front of the engine compartment?

least intrusive method I found is to remove fog lamp relay under the passenger side dash, bend the grounding leg sideway and up (so that ground circuit is defeated), solder a wire on the ground leg and finally ground this new wire by hooping it under a 10 mm nut close to bottom of passenger side A pillar/front edge of passenger side door.
Soldering on to relay leg is pretty easy because most, if not all, relay legs have a hole where you can thread a wire before soldering.
