Title: Golfing Problem.
Post by: Wigs on 20 June 2006, 18:11

Hey guys and gals, I was wondering if you could help me out.

I recently got my hands on a standard '88 MKII Golf, and a free Pioneer DEH-P3500MP Head Unit. Now, I've removed the stock casette deck, and plugged all the connections into the ISO block that came with the Pioneer unit, but it doesn't want to work. The tape deck still works when I put that back in, so I was wondering if any of you guys might know / have an idea what's up with it? The fuse is fine I checked that, and the wiring seems to be fine, otherwise my casette deck would be dead too..

Any help would be hugely appreciated, as I have a long 'ol journey to make on Friday, and I really don't want to do it in silence..

Cheers in advance.. xx

I know this is a stupid question, but in my past experience it hadden't been connected. When headunits are brand new in the box from the factory the red and yellow wires aren't connected so that when you get them you can choose to wire them up permanant live or switched ignition. also some cars work backwards so you have to wire the red to the yellow and visa versa.

so are the red and yellow wires connected?

The VW wiring blocks are wired the opposite way round to most modern head units, plus the ignition live wire is normally not present.
You'll need to run both red & yellow wires to the VW red wire using the spade/bullet terminals like Dizzie said :)

Ok I've swapped the red and yellow wire around, but still it's nothing on the new HU. The old casette unit still works with the swapped wires though.. Am I being totally oblivious to something really simple?

That is what you meant with wire swapping, right?

Man, why can't things ever be easy for me?

right what you need to do, is join both the red & yellow wire on the HU side, to the red wire on the plug side.  Basically you only have 1 live feed from the Golf plug, and the stereo needs both a live & an ignition live, so you have to splice both into the live wire from the Golf plug :)

I have a both switched live and a permanent live in mine, I should know this because I hard wired the stereo in with bullet crimps. Bugger these blocks :)

Riiight I'm tempted to go try this out now, but as it's almost 11pm, and raining, I don't think I will. I know, I'll try it before work tomorrow. Sorted plan.


On the offchance that this doesn't work.. I'll either go get it fitted for free in Halfrauds, or buy a new unit maybe. f**k, student income rates are the worst.

maybe this pioneer unit is faulty?

Yeah that's what I was thinking.. But the mates mum I got it off assured me it was in full working order before I took it our of her R5. Also robbed some speakers that as far as I'm aware are the perfect size for the dashboard mounts. Stoked I say. Just fitting them's gonna be a pain in the arse.

All-f**kin-right, RubJohnny, I thank you, as now it all works.

Spent about an hour getting the dash speakers out, only to find the ones i have dont fit, so off to somewhere to get some. (anyone recommend a place to get? Web deal maybe? And are they 3.5" speakers in the dash?)

Ahh so many questions, but so many thanks for the dudes who helped.

Time to browse the rest of the forum :)

:cool:
Have a look on ebay, JBLs are great speakers for the money :)

Yeah I'm gonna have to, got quoted £40 for a pair this morning.

Also, am I right in understanding, that splicing the red wire from the heater wires, to the red wire that reaches the HU will allow the cd player to only be used when the ignition is switched on?

Not the red wire, you want the black/yellow wire :)
If your MK2 is a pre 90 spec (hazard switch on dash) then there are 2 groups of spade terminals on the rear of the fusebox, 1 side live the other ignition live.  You could run a wire from here which would be easier and save you chopping splicing any existion wires :)
If you have a late MK2 (hazard switch on the column) theres a 'key in ignition' feed on the rear of the ignition switch (pin 'S' or 'SU' if memory serves).  This would make the radio switch on as soon as you insert the key in the ignition, which will save the coil from damage if you sit with the radio on without the engine running for long periods of time.

Wait now, Yellow and black from the fan control, to the red from the ISO block?

Got me an '88 model (F reg).. Found the fusebox, can't be arsed to get behind it though I don't think.. I'll just do the splicing work, much easier than getting upside down under the steering wheel an that..


Another random question.. Is it worth chopping old springs to lower, or buy new ones? I can guess the answer immediately.. Don't even know why I asked.. HUmm.. Is it easy to change the springs?

Title: Re: Golfing Problem.
Post by: rubjonny on 28 June 2006, 08:14

yep, the red/yellow is ign live.  Red on a stereo ISO block is normally ign live, and yellow is battery live.
To get behind the fusebox all you need to do is remove a few screws, drop the dash under tray, then take a clip off the side of the fusebox & it'll drop down.  Couldn't be easier ;)

As for springs, well I'm glad you figured out the correct answer on your own ;)
Not difficult to do, rears are dead easy and fronts are a little more work.  You need a spring compressor to do the fronts, and a special strut tool from GSF helps too, the haynes has the procedure in more detail.

Didn't bother with that in the end.. I just built a box for my 10cm speakers as they didn't fit in the dash and looked ugly. So now they sit down by the thingy, erm, in the center at the bottom by the little hidey hole.. I'll maybe get a photo on here sometime to explain it all.

I really want to drop my car by a good few inches, but I can't be arsed, and I don't have the knowledge to do such a thing, and I can't afford to fork out £50 for a new set of springs. I just want my car to handle better on the country lanes around me on the 7am rush to work an that..

Life is tricky guys and gals..
