I am not 100% sure but my Aus delivered 1997 V70 T5 has the same sunlight and lock light and is the immobiliser light has never flashed in my 6+ yrs of owning it. No idea of how many pins it has I am to lazy to pull it out but I have always wanted it to flash when the cars locked like the 90's falcon smart lock transponder in the corner of the Windscreen.
Just for the nostalgic period look lol
I might do another check tomorrow to see whether its the black relay (VGA2) that's cause it to flash for the programming.
With the Basic Alarm system (which has its own individual receiver box beside the glovebox as per my post somewhere on this thread), the manual says it should flash red when dead locked (2 pushes of the lock button) but it doesn't which makes me think its activated by the black relay. Update to follow!!
I've been chasing the same thing nostalgia :-), may be best not touch it as your sure to break clips and anything plastic haha
Bit random but I remember a couple of years ago I jacket the car up with the doors locked ( alarm on ) and remember the red led going mental 
You may have a level sensor which was an accessory part for the Volvo guard alarm and plugs into the relay. 'I have a glass break sensor' for mine…. This will be in a future post haha
Guessing you dont have a horn mounted on your firewall that should have sounded whilst the alarm/red light was going off?
Yep exactly right on the sensor . Stuart was talking about the break glass sensor as well , I've looked into it in from the past but not gone for it for some reason ( still in my watch list ) .
The horn bulk head hmmm I've thought about this for years now , done nothing about it . If I was going OEM I'd have it for sure but I've seemed to stray away from original with my R..
rado there's heaps of glass break sensors on ebay UK.
I've got one and also got the horn and bonnet latch sensor.
Just making sure any blank plug I find for optional accessories is filled haha
Stand alone alarm horn
Break glass sensor
Reqiured relay
Alarm harness that plugs into main harness
Bonnet latch with micro switch
Genuine factory Central locking & alarm fob
Broken glass sensor
I've now got factory central locking and factory alarm set up in the 850R
242GT Thanks for the pictures, I've pretty much got all of them parts and installed the horn and bonnet latch/switch last night.
With regards to the glass break sensor, where does this connector plug into:
The only item i need to buy is the keyless entry fob, i looked on Skandix and thought their Black Friday Sale might have offered a discount but it looks like they only have a sale on caps, bottle openers and the like :-/ https://www.skandix.de/en/spare-parts/body/bootlid-bonnet-doors-sunroof/locking-system/remote-control-locking-system/1019759/?srsltid=AfmBOoqqbEAPZp8Gen3pKXZRB2EKc1vnRNAJQ4R1wHcK-k0YTqH7Bhue
Any tips on programming the fobs? I'm assuming i just buy the fob and then program it as per usual with the 5 key cycles?
Also, dos your indicators flash when you lock the car?
It looks like your horn is mounted in a different location? I also noticed your running the v70 style wipers which means you can use the nut caps that lot of people seem to ask about online.
I've deliberately didnt mounted the horn in the factory spot , which is down on the firewall near the turbo as it would be subject to the heat coming off the turbo , its also far more practical where its mounted now for the harness plug and function , sound .
The harness plug was literally right next to where I mounted it , I found a hole that is already in the metal lip that runs accross the top of the engine bay, just run your finger along the lip under the plastic cover and use a step drill to carefully drill a hole in the plastic making sure not to touch the painted lip below , its under the plastic cover in the middle in front of the screen and covers the cabin filter which I've also installed as 850's didn't come with them.
Yes , I've converted the wipers to the S/C/V70 series wipers and now have drivers side (right hand) working perfectly in any rain event.
The caps are hideously expensive for genuine from suppliers ( $24 plus postage) so I've used a different manufacturers cap with an O ring inside to create a tight fit so it functional and looks original.
Yes , all blinkers flash as per factory with the fob , the smaller rectangle button operates the alarm , Stu from Voldat helped out with the setting up , I bought parts from overseas and Stu to complete the reqiured parts and install.
The good part is that on the 850 , the wiring harness is all plug and play ready to go , so as you get the parts , wiring up is very easy via ready to go plugs in the harness.
I'm a fussy old fossil , so now everything works in the cars entertainment as it should including the CD player , both stacker in boot & single player in dash.
I use a blue tooth cassette to connect my phone to the cars speaker system so I can use google maps and Waze as a good sat nav.
This has allowed me to keep the 850R as per factory original as possible both inside and outside the car
Ah I see. Looks tidy 
why do people upgrade to the v70 wiper arms out of curiosity?
I know of some at a local wreckers and also have caps in my shed.
Keen to see where that glass break sensor plug goes into
morch_66479 the standard 850 wiper dosn't like the Australian heat and as they get older twist out of shape and don't wipe the screen with full contact on the drivers side to the point its dangerous in storms trying to see and pass rego checks.
The factory wiring diagram will show where to plug and play the alarm.
242GT
This makes sense and maybe this is why my passenger arm is nearly touching the bonnet. Maybe i should upgrade to the V70 arms.
I tried looking at the diagram but still none the wiser. I understand the green plug goes into the relay but the 2 pin plug might make more sense when I go to install.
I was chatting to you on Messenger about your spare amp, I've since managed to get my hands on one: 1384848 - 4x50w.
My GROM system has allowed for Bluetooth connectivity and is also able to connect my old iPod to the radio too.
Soon i should have the audio, alarm system & headlight wiper conversion completed - as you've already mentioned its super handy having all the wiring tee ready to plug and play 
I'm in two minds on the washer wipers on the headlights . When I had the car respray I had both sets painted , I like the look with them but prefer the smooth look without . One of the motors needs a rebuild so I've stuck to without .
Bit of a late reply to the headlights wipers lol
As far as I know there's a couple of different types , my car had an Australian after market central locking module unit plugged into the harness behind the glove box , but ever since I had the car it kept flattening the fob batteries within 24-48hrs and had very poor range, about 2 metres
Hit n miss with my fob , sometimes around 6 metres sometimes 2 metres , Volvo's 
Very pleased with the end result of the genuine parts I installed, took a while to collect all the bits a pieces but tested all the sensors and the all work.

Not sure, I think I sold it on here but will have a look 
Found it
Luckily still in the keys boul lol
LMK if you want it
