Hurtenstein: That was one of the wiring options that came with the CI 65 unit, but it didn't work either. Because I only get a momentary earth from the brown wires from the alarm unit (think of it as a negative 'pulse') the doors unlock but lock straight way once the negative pulse goes away - the relay just goes back to it's resting position. If I do it the other way around and have the circuit normally closed (so the doors are always unlocked) the reverse occurs - the negative pulse locks the doors, but they immediately open again once the pulse goes away.

bumpstop: Thanks for that too, I'll have a read. Awesome relay guide by the way :-) it didn't seem to work when I tried it from Fobz's guide, again because it's only a negative pulse I get, not a complete ground, which it seems to need to keep the doors unlocked. The diagram on page 6 looks waaay to hard, I think I'd give up and take it to an auto sparkie before I went there!

Fobz: As you say mate, maybe getting them together is going to be the only way to work this out.

If you have it wired correctly and the factory CDL is operating properly it only needs a pulse.

Here is the offending wire:



If I earth the wire on the left running back into the main loom, the doors unlock. If I take the earth away, the doors lock. The wire on the right doesn't seem to do jack.

So that wire up above grounds out when the drivers door is unlocked, telling the CDL to unlock the rest of the doors.
If you join that back up, and use the 2 relay box you bought to run the drivers door solenoid directly, It should be a winner.

Problem solved .. by the very awesome Bumpstop!!

Turns out the problem was with some corrosion in the connectors in the big white plug you can see in the picture. This meant the signal coming back from the door side of the wiring wasn't getting through, so no amount of faffing around that I was doing was ever going to work

I went to see Bumpstop at Westside Car Audio and he diagnosed the problem and fixed it for me on the spot. Big props to him and the guys at Westside for looking after me today! Nothing like getting someone who does it for a living to sort things out - which highlights the fact that if you don't know what you're doing, get a professional to do it before you fry something

Big thanks also to Fobz and Hurtenstien for the multiple phone calls and messages, great to get such good help from a forum post, it was much appreciated.

I think I owe beers all round!

Cheers,

Wrxpc

You're welcome mate, and was nice to meet another P-WRX member
