Nevermind, I reviewed it now.

So Im guessing, in the stock setup that 6 is a 12V source, and in DRL mode, 8 is hooked up to 7? Then when switched to high beam, 7 is grounded and 8 is hooked up to 12V?

Correct me if Im wrong

 

I read the FSM some, it says 6 and 8 are always battery voltage and 7 is always approx. 0 v.

If this was the case, the High beam connected to 6 would always be on full power :S

 

1. If you want them to be switched on/off whenever you want, your best bet is to hook up an Auxillary switch. this can be done a ton of ways, grab IGN switch power from somewhere like the DRL imput, and run the trigger from in-cabin. You will still have to cut in to the High beam wire, but not the ground side. This will make it illegal though, if anyone checks, because the DRL's won't come on automatically when wired this way.

2. & 3. Not from what I see, #6 Turns on 12V+ when
A) high beam is on
B) drl is on

A) When high beam is on, Terminal #7 (Ground) is a Chassis ground
B) When DRL is on, Terminal #7 loops around, out through #8, and then finally through the LEFT high beam and to the LEFT high beam CHASSIS ground.
It's this action that forces the Power to be split between the two High beams during DRL operation, because it changes the circuit to a SERIES circuit (in-line)

Does that help explain it?

 

I would probably just run a relay to a switch in the cabin which is hooked up to the cig lighter. The light would be nice at night because it will actually throw an extra 600 lumens.

Do we have different FSMs or am I interpreting it wrong?

The way you described it is how I initially assumed the terminals would work, as I queried above,but when I looked it up in my FSM I saw this.



I can always check with a multi meter though.

 

You're just reading it wrong, those terminal voltage charts can be confusing, the conditions in which there is BATTERY VOLTAGE are listed in the center column.

If you want to see when it's on/off you read power-flow description. I can pretty much assure you that the way I described is how it works without even reading the description though.

 

Cool, I just read somewhere that it expect continuity between 7 and 8 when DRL is in effect.

I learned something new about the G / reading schematics today! Thank you!

PM me your paypal if you want the $10

 

that's right there WOULD be continuity between 7 & 8 when DRL is ON.
This is because instead of being a normal ground, 7 is hooked to 8 while DRL's are on. This is the "loop" I was talking about that creates the series circuit.

When the DRL's are off, terminal 7 has continuity to Ground, but NOT to 8, which allows the high beams to run full voltage when they're turned on.

This 'loop' at terminal 7 will be bypassed, 7 is left disconnected once you follow my diagram.

 

Thats what I figured after your first post

 

Oh, and if you do check the Voltage with a multimeter at terminal #7 while the DRL's are on and everything is connected, it should actually show about half voltage (around 6.5-7 Volts), if you do measure it, don't be alarmed by this, this is normal.

 

With it unplugged, shouldnt I see a full 12 V since it has no connection to ground?

Also, I was just planning to check impedance to see where connections are made for sure

 

will the 03-06 sedan side view mirrors fit the 07-08 sedans?

 

Terminal #7 will never have power except when DRL's are running, and it's plugged in.
At this time power will flow through that terminal. What you'd be measuring at terminal #7 at this time would actually be like measuring voltage drop, which is why you see half voltage, because the power has already flowed through one of the High beam Bulbs, sending the rest of the voltage through the DRL module, out terminal #8, and through the Left High beam bulb, and finally to chassis ground over at the left Headlight ground.

Terminal #6 will never have power with it unplugged unless you turn on the High Beams, then you'll have battery voltage at that wire.

 

I've never tried to change them, but I've seen both and can say pretty darn sure they won't fit, no.

 

is the wiring harness the same?

 

So it, s time to replace my tie rods. What's the difference between these 2? One says it comes with inner and outer tie rods but it doesnt say anything about tie rod ends. The other one comes with tie rods and ends and it's cheaper http://www.enjukuracing.com/products...B47%7DG35.html or http://www.autocityimports.com/0307-...it-p-9242.html
