While waiting for parts, I thought I'd get the loom passed through the nice 80mm hole I had to drill in the bulk head, and start unraveling some of the mess!
Wiring isn't my strong point (At all) because I have zero patience, and I'm usually very good at fucking shit up with a power-probe! haha
Unfortunately, when I was stripping the Laguna, in the cold, and rain, just after Christmas, I'd thrown all the shit and scrap in the back of it, meaning all the rear section of loom in the car was burried.
Rather than unload it all, to retrieve the entire loom, I had a minute of utter madness and just went through the loom along the bottom of each door shut with bolt croppers. Assuming I'd only need what lies behind the dash and in the centre console.
Unbeknown to me, all the earthing rings / points for the dash loom must have been slightly after where I've cut. So I'm left with a dash loom which wont power much up.
Neal has been fucking excellent at helping identify bits and pieces, but there is only so much he can do to assist my sheer stupidity.
I've identified all of the black wires. Some of them buzz out as ground already, some are open circuit.
Had a little play yesterday, and by grounding some of the thicker black wires, I'm getting UCH action. The courtesy lights comes on of I press the unlock button on the key card.
When I insert the key card, the flashing red immobilizer light turns to solid red on the clocks. But I'm not getting an ignition cycles. (I'm also missing the start/stop switch!)
I forgot to whip it out of the dash before my pal took the car away on his truck. WHATADICK!
When I remove the key card, and press the lock button on it. The UCH makes more noises, and the clocks / LCD display lights up for a second.
So I'm pretty sure there is either something still not grounded correctly, or there was a module / fuse box in the back of the car I left behind!
I'm going to split the loom open today and remove all the tesatape / plastic conduit, trace all the black wires back to where they come from, as some may be canbus etc. I'm struggling to find a wiring diagram online for it.
I've been told by more than one person now, that if I have the Immo removed from the ECU, I can plug it into the engine loom, wire the OBD socket in, and power it up with the ignition.
Wire the starter solenoid up to my original ignition crank wire, and when the ECU receives the cranking signal from the crank sensor, it'll fire.
This would be my preferred choice, as it'll allow me to do away with everything in that passenger footwell.
However, if it's not likely to work, I'd rather put the £££ spent on immo removal, towards a stand alone management system! haha
Any ideas?
