stereo wiring help

[parfittron]

Hey guys, I'm mid way through installing a new stereo head unit and we cant seem to find any consistent power to the harness, so was hoping someone may have some expertise to help?

We have found the ignition triggered power, but the line we expected to be the constant, based on wiring diagrams I've found and the install in the forum directory yielded nothing.. Checked all the fuses under the bonnet and dash for the audio.

My trip computer ha didn't turn on when switching the ignition so we pulled it out and couldn't find power there either..

Any ideas??

Cheers
Chris

Most of us have run a new wire from the battery to power a stereo as they demand quite a bit of power...edit sorry was thinking amp not head unit ...existing power supply is fine..

[Cowboy Dave]

I disagree with that. Separate power for an amp, sure, but I reckon most use the existing wiring to power the head unit.

[parfittron]

Ah really? Fusing it separately?

I would have expected to find at least some power elsewhere in the old harness though so I'm thinking we have either done something wrong or have blown a fuse but have checked most of them.

[Cowboy Dave]

It's always best practice to do these installs with the battery disconnected so you don't risk any shorts and blown fuses. Is that what you did or were you working live?

It would be useful to know what model you have, what the stereo looked like and what your putting in as well as how you're putting it in - the easiest way is with pre-made plug and play harnesses but by the sounds of it you're doing something more old school?

Try fuse number 13 in this diagram, should be a red one. Picture needs rotating obviously.

If your interior lights are still working (map lights and dome light) then it's not that fuse.

08 ml cowboy. Just the stock single din with trip computer up top.

Was just installing a pioneer Bluetooth job, single din. Old school style.

Yes, working live.. My brother is a sparky and doesn't believe in taking the battery off.. Not saying I agree...

I've just installed a head unit and the power was fine I used an aero pro plug kit..so it was plug play ..but run new power for my amp...from battery.

[parfittron]

Turned out to be that we'd blown the interior light fuse.. Worked it out as daylight was fading and about to call it quits. Problem solved. Odd that it is connected ?

[Cowboy Dave]

So are the interior lights working?

[parfittron]

They weren't. Hadn't noticed earlier. Replaced that fuse and got power to where we expected, so finished hooking it up and we were good to go.

[Cowboy Dave]

Sweet.

Cheers for the help!

UHF and new head unit in today, duel battery and brake controller in last week, so all the wiring is good to go.

Hi which brake controller did you wire up parfittron?

Tekonsha primus IQ.

Just found Aeropro are doing plug and play harness, steering wheel control interface for buttons and a double DIN fascia for the MQ.

Hi,
Can anyone help please?
I have a 2013 Triton GLR (tweeters non standard) and scored some tweeter speakers from a GLXR (tweeters standard). The harness in the door has a small plug for the tweeters which has a white/red wire and a black/red wire. These two wires disappears into the loom within the door. Where do they go??? The plug fits the tweeters but when connected there is no sound at all from the tweeters.
I have replaced the head unit with an after market unit everything else works fine.
Any ideas?
Thanks

No where apparently.

Sorry couldn't help myself

See below

I would say you are missing some part of the loom.

This is where they would have come from in a GLX-R

Hi ag9111.
I left myself open to that one!!!
Thanks for the info. The way I read it (rightly or not) is that the tweeters in the GLXR connect to an external OEM amp because it has a better sound system than my model.
In some other models (?) the tweeters are in parallel to the door speakers. Does this sound right?
I assume (be careful here) that the images below the wiring diagram represent the different connectors to the head unit with the associated pin numbers.
How did I go?
Thanks

[ag9111]

Correct.
they are the pinouts for the various connectors and correspond to the connectors in the schematic
