Hi People,



This is my first post so be gentle.



With regards to putting an after market stereo into a vectra it is possible but difficult if you have the 2004 or 5 models. I have a full Kenwood setup in my car which i transferred from my Astra. This is how i did it.



Parts Needed



Autoleads Double Din removers - PC5-110-H

Autoleads Car harness adapter - PC2-85-4 (says Astra on the pack but is the same)

Autoleads Single Din adapter

Tork Screwdriver

Small Flathead screwdriver

Lots of Coffee !!!!!!!!!!!!!

Volt meter if you have one, if not don’t worry



Now before we start a bit of information that i have collected as i started to fit the stereo.



In late 2003 Vauxhall changed supplier of the stereos to Blauphant as a result they have a BMW connector onto them so don’t buy a harness adapter that you see on e-bay as this will be the one for the 2002/3 models when Philips were making the stereos. With regards to the power supply car manufacturers are changing the voltage feed to the factory fit stereos as a result people are having difficulty in fitting an after market stereos, for example some are making 6v stereos and as all after market units need 12v, this means that you will have problems fitting one. Luckily Vauxhall have not done this yet but I have been told that it is on the cards.



2002 / 3 models



If you want to fit a stereo to this years models it is quite easy as the majority of the stereos are the Phillips versions, if you do have a Blauphant then refer to the 2004/5 instructions. If it is Phillips then one lead will do, follow the instructions below to remove the existing stereo and get for yourself a standard Vauxhall harness lead adapter from Halfords, you can either get a Halfords own make or an Autoleads version they both work the same. Connect one end to the harness connector and the other to the ISO connector with the stereo and away you go.



2004 / 5 models



With regards to this years models it is a bit more difficult



To start with remove the existing stereo with the removal keys, be careful and take your time not to rip the front off the factory fit stereo. When you have removed the stereo take out the plug behind, it is held on by a locking piece push in the 2 clips at the side and pull up



Next look for a tork screw at the back of the cage in the dash







Remove this screw





Next remove the cage; this is a bit tricky so take your time. You will need a flat head screwdriver to edge up the front of the cage, when it becomes free edge it out.







Don’t worry of you bent it it’ll bend back.



Next fit the Single Din adapter face and cage from you after market stereo, also fit the Autoleads harness adapter to the lead in the dash







You will notice 2 wires on the adapter a yellow and orange, this is for the Astra to allow a feed to be taken from the Hazard light, not needed on the Vectra. These need to be taped up as not required.







Now comes the hard (ish) part. Connect the other end of the adapter to the ISO lead from the after market stereo. On this lead you should have 3 wires with bullet connectors on them these are the power feeds to the stereo. These will be connected to 2 from the harness.

2 x Red and 1 x Yellow, one will be not connected to anything.


Now a bit more info, in 2004 another change that Vauxhall made was with regards to the ignition feed to the factory fit stereo, they have changed it to a 3v feed, after market stereo need 2 x 12v feed to work either



1 x power and 1 x ignition



Or



2 x power



The latter 2 x power is the only way to wire an after market stereo to the 2004 / 5 vectras. So what you have to do next is



If you have a volt meter




Tracing the bullet connectors back to the connector, turn the ignition on and check the voltage going down the 3 wires you will need 2 x 12v feeds going to the unit. When you have found them connect the bullet connector so the feed goes to the unit, you will end up with 1 bullet connector not connected to anything. 90% of units the 2 wires should be red but it is worth checking.


If you don’t have a volt meter



The only way to do it is by trial and error, you won’t damage anything as there is no larger feed than 12v.



Now when it is wired up the stereo will stay on when the ignition is off so you will need to remember to turn the unit off this is because the ignition feed is 3v and this is not enough to power the unit.



Hope this helps any questions please pm me.

Yes, the 3 bullet connectors are on the iso connector from the after market stereo. you need to find 2 live feeds from the original wiring loom via the Autoleads harness adapter. and route these to the stereo to provide the power. Remember that the only way to install one is to have it on a permenant 12v feed so you will have to turn the stereo off or you will have a flat battery.

Cheers for that m8 i shall have a look in the morning and let you know how i get on

I took a 12v ignition feed of the cig lighter to run my bluetooth kit. This will do the trick for the sterio too.
