Check any documentation Brain gave you, but for my Reverant MS3 there is o2 power, o2 ground, and o2 signal built into the adapter harness. You want to use the same power and ground as the MS, not your radio circuit.

 

probably not on his ms3x harness... just the o2 input on the pink wire.

 

WTF is the confusion on the dimmer? ground to bright, 12v to dim.. how ******* hard is that?

 

I was just going to avoid the dimmer for now as I was having a tough time finding a 12v power when the headlights were turned on. But if you have a suggestion of which wire, I would be happy to hear

(I read that it was the red/black wire that is hooked up to the dimmer ****/many other things in the dash, but knowing the fragility of the dimmer circuit in these cars I didn't want to try it).

 

Okay so O2 signal and power are figured out. I also found in the manual that the white wire needs to be grounded if not used (I'm assuming any ground is fine) and the unused black wire can just be electrical taped.

Suggestions where to put the white wire (on a 1.6) are appreciated.

So now its just ground. Where do I put it on the MS3X? I don't see a black wire going to the center auxiliary section of the harness.

 

Are there any ground wires coming from the MS? They are all connected internally unless brain did something wacky. So you can use any ground wire coming from the MS3. Read:

I just spliced into the rd/blk wire here. Seems to work fine on my car.

Well if it hasn't friend your dimmer switch yet, I guess I might as well give it a try

That diagram helps a lot, thanks FRT. But it confuses me as to which pin I'm actually supposed to tap into for my black wire. I would assume anything 7-19? And that also brings me to ask, should I ground the MS3X's case itself to the block? Thats what it said in the diagram, but I thought these are all grounded internally and to the case and everything already.

Don't worry, I'm so close, a few more stupid questions and you won't have to hear from me anymore

 

I just threw up in my mouth a little bit over your interior

 

Oh come on now, Vlad...That's just dust, a few leaves and rocks from living the mountain life...not to mention bad lighting from a shop light.

 

What? Where does it say that in the diagram? Grounded internally? huh? The MS has the potential to have many grounding wires depending on how it is built. You will need to ask brain for the specific grounds that you have available to you, but they should be all black wires from the MS. All the grounds are interconnected inside the MS. Because of this you can choose any of the ground wires to ground your sensors. Then the others grounding wires will ground to the block. Nothing about the case, only wires that go to the circuit board inside the case.

 

lol alright....I'm ocd about interior cleanness

 

Black goes to the Black ground wires of the MS harness. Use the ones closest to the center connector; they will be paired on 2 pins.

White goes to R/B wire on the radio.

Brown is unused. don't ground it; just dont connect it.

Yellow goes to the pink wire on the center of your MS harness.

 

Theres the good stuff, thanks Brain!

I'm hoping to get out of work early today and go finish this stuff up.

 

never mind the socks and sandles with toe holes worn through lol


this thread delivers btw

 

Must always wipe the *** off the seat.

 

Make me a shifter like the one in your thread and I'll forget you ever spoke ill of my socks and sandals.

 

lolz pm me if you really want one
and my interior looks about the same

As if there was any question.
