Sometime ago I saw this image in the clark web and I keep it. Do you think it would work?

Yep, another idea would be to connect it to another port. Im already using the mgs ports and the aux one. Unless Kevin comes here with clues of how to make a better wiring, I will probarbly put the rear lights in one of the other connections in the 8 pin port.
I would like to connect it to the rear lights port, but as far as I know is only for going backwards so I cant use it unless it can be switched on and off on my will in some future firmware update.

My recommendation is either get all new leds with same specs (but different colors) and then you can calculate and add proper resistor. Or connect headlight leds to 1 output on asp, and tails to another. There's plenty light outputs to choose from: headlight, taillight, aux light, even mg2 can be used if you're not using it for mg. Asp is really versatile as long as you think outside the box

I rewired the leds like the Peregrine´s diagram. If I wire one led like that, the headlights will bright like the first attached picture. If I wire 2 leds, will bright WAY less, like the second picture. If I wire 3 or more, no one will work.
What am I doing wrong? Sorry if the wiring photo is a bit confusing, that is just a provisional wiring.

The small connector next to the eight pin is the machine gun (and works ok).

This make it out that the fault is with Asp when it is poor wiring that is the issue NOT Asp.
Of course im not saying that is an ASP problem. If anybody understood that, I must say it is not a boards problem. My poor electronics knowledge and dramatic soldering, is. Lol
Rad you need to rewire your circuit such that the LEDs are in SERIES. I suspect that the Headlights are actually in series (this is how they would be factory wired) and your Rear lights are also in series.
Yes, that is how I wired them.
But you have wired your headlight combo in parallel with the rear light combo. So the current only flows thru the side with least resistance that being the rear leds.
I think you found the problem. Im going to try to find how should I modify it and see what happens.

Rad your circuit shows your LEDS in parallel - this means that the current will most likely only flow thru the LED with the least resistance. All other LEDS will be OFF.
You should wire them such that the LEDs are in series. All of the wiring I've seen from HL have the LEDs in series so....
I'm sure you guys think I'm too cranky but how can I not be...
"Now with the ASP I cant make them work. If I plug all 4 leds, only the rear ones work. If I unplug the rear ones, the front ones works."
This make it out that the fault is with Asp when it is poor wiring that is the issue NOT Asp. The 5V+ supply on Asp2 is 4 Amps. I have made a big deal of this as it is more than ANY OTHER controller. A Led requires 20 milliamps (0.02 amps) of current. So you can light up to 200 LEDs with 4 amps of current.
Another VERY VERY important thing here is that with LEDS it is NOT voltage that is critical it is CURRENT. Some LEDs have built in resistors and if they do then they will require specific voltages but most LEDs do not have these.
If you are running a LED direct without any external resistor then the resistor is internal. So if you have a 3V LED, assuming 20 milliamps then that LED has a resistor of R=V/I, = 3/0.02 = 150 ohms. Again, most LEDs do not have such resistors and can be used with any voltage.
If you are at all concerned about blowing a LED add a resistor 220 to 330 ohms.
HOWEVER, THERE IS ALREADY SUCH A RESISTOR ON ASP. Asp is limiting the current ALREADY on all LED outputs.
"As I said Im using no resistor, but I have been driving my sherman for hours with the front leds ON and had no problem." No you ARE using a resistor and if there was not one on the Asp board you would have no working LEDs
Rad you need to rewire your circuit such that the LEDs are in SERIES. I suspect that the Headlights are actually in series (this is how they would be factory wired) and your Rear lights are also in series. But you have wired your headlight combo in parallel with the rear light combo. So the current only flows thru the side with least resistance that being the rear leds.

PS ... For clarity to be ultra safe DO NOT repeat DO NOT take supply for LEDs from anywhere else other than the LED connectors. In particular the ground return. The ground return V- or V0 is protected with the resistors on all LED connectors
