Here it is:
https://www.newtriton.net/phpbb/viewtopic.php?f=101&t=22996If you know what you're doing then wiring an MQ is not that difficult but the factory wiring is a bit tricky with some sections only carrying computer signals, others low tension and still others high(er) amperages. Then there's the high voltage HID bit. WUNSIE, you'll be pleased to know that it's only 18,000V on startup, not 20,000V, and drops down to just 85V once the arc is established. Still enough to give you a decent kick.
The factory harness makes it easy and prevents mistakes. But, I think it's intended for driving lights and I'm not sure that it includes provision for indicator and parking light repeaters on the bullbar. For this reason, and the fact that I expect a lot more instances of this question, I'm going to detail here a basic tutorial on where to connect indicators and parking lights for a bullbar on an MQ. should work for MR as well, but I haven't checked the wiring diagrams.
I'm also going to assume at least a basic level of auto electrical competence. If your idea of joining wires is a Scotchlock, you can't use a multimeter or don't understand Ohm's Law or the concept of voltage drop, then you really should find someone else to do the work for you.
First thing is that all this information is available in the online manuals (for both Gen 4 and Gen 5 Tritons). You really just have to look. But their wiring diagrams can be complex so separating out the steps may help those who can't read the diagrams. The same process can be applied to other things, such as finding the connectors for foglights or for driving lights/lightbars, although there are some specific Mitsubishi harnesses available that make installation of these items very easy, given that some aftermarket harnesses, as supplied by driving light manufacturers, can be intended for Toyotas, which use a very different switching system and need modification to work in a Triton.
So, starting with the turn signals, we can see that we need the blue/white wire on the left and the yellow/black wire on the right. These can be found on connectors A17 and A35 respectively.

Then, for the parking lights, aka position lights, we see that we need the sky blue wire on the left and red on the right, on connectors A17 and A35 respectively.

There is usually precious little extra slack in the factory harnesses in these areas. You may have to release the harness further back or remove the headlight to get decent access to be able to crimp a joiner in to these lines. Make sure to cover joiners with glue filled shrink tube to ensure they stay watertight.
