Hig beam wire won't trip relay

[thorvald]

Every car, truck og suv I ever have wired I have wired the same way when it comes to extra driving lights.

With my Montero Sport 2000 I can't get it to work. The only way I have gotten it to work is to wire the trip wire to the top thin wire on the H4 socket. That should not be the way to wire it. Any sugestion to how I should wire up extra driving lights on this SUV?

The only thing I can think of is that I read some European and Japanese vehicles wire the headlights 'backwards' from what is normally seen. I remember reading about this 4-5 years ago when I was researching stand-alone headlight harnesses. I remember it applied to some Toyotas and some Mitsubishis, but not AFAIK to any of ours. I THINK it had something to do with a positive ground rather than negative ground system.

I don't know how much this helps but maybe something to research. I've never had issues with the headlight wiring being anything special. I just installed CE's aux harness - the same one Tony runs on his old muscle car - on my '97 Sport and everything worked fine. That runs feeds off one of the OEM plugs to activate two relays, so ....

Have you checked the FSM wiring diagrams?

Yea you need the wiring diagrams. Pretty sure bulb wiring is the same regardless of location. One wire is ground, one high beam +, and the other low beam +. Hook it to low beam and they come on when you turn the lights on or they come on with the high beams if you hook into the high beam +.

I was so sure I added the wiring diagrams, sorry for that 🤗

Ah your spec has DRLs. Interesting... I see an auto leveling feature to. I'm not familiar however with how the DRLs work on these but it shouldn't matter. Regardless how its wired or switched if you wire the running/driving light relay coil to the energized wire from whatever circuit you want to use to activate they should come on.

One thing I didn't catch onto was you said yours is a 2000 but thought all those used 9007 bulbs. Region may play a role in this but just want to make sure we are on the same page so as to not short anything out. Is everything in stock form? Also need to make sure the wiring schematics are for your specific make and model.

Having said it appears that Red w/ White stripe is ground,
Red is high beam, and
Red with Blue stripe is low beam.

I cant see some of the diagram clearly though. You can always test with a multimeter before actually making any connections. Good practice to get into.

I should have mentioned that I'm from Norway and that I have a European model.
I talked to a local Mitsubishi tech and he told me that the Mitsubishi models are wired to switch the connection on the negative side.
To wire this just wire the nr. 85 and 86 to each side on the H4 connector.
This also do that you don't have to ground the relay. I just now redid the wiring this way, and it worked perfect.

There you go. Yea after looking at your schematics it appeared to show that it is a switched ground setup. That was part of what I couldn't legibly read was the connection points that picked up on each block. You didn't have to make another connection to the headlight harness on the ground. Any ground would work and would've kept you from splicing another wire. Also the switch isn't necessary as turning on the high beams acts as the switch. If you wanted to be able to turn them on and off that way just run that one wire straight off the battery + instead of the highbeam wire.
