Wiring looks fairly basic on ecu to be fair. Daft question are ign live and permanent 12v the right way round? Where does the permanent 12v go to? If it goes to uch it might shut it down.
It is fairly basic to be fair. In terms of wiring the S3000 into my Meg loom, to get it powering up, and communicating, it needed an ignition feed into CD1 (Yellow wire), that is it. The rest is all ready wired up on the relay plate.
Of course, things like starter motor cranking signal wire, reversing switch etc, needed re-wiring onto the Meg loom directly as they are not done via CAN like on the Laguna.
I sussed out the issue with the 12v feed to the crank sensor. VERY schoolboy error on my behalf, and will teach me to assume shit, rather than buzzing wires out with the multi meter.
Obviously, I had to cut the plug off the Laguna crank sensor wiring, and solder on the plug from the Megane loom, as the JB3/JC5 boxes run the old style crank sensor.
Where I went wrong, is I unbolted the sensor out of the PK6 box, and plugged it into the first plug it fitted in, on the Laguna engine loom, assuming it would be the only one of it's kind.
WRONG.
It shares an identical plug with the bloody AC compressor. Haha
Needless to say, I've located the correct plug now, re-wired it, and have a good strong cranking signal on Delphi.
Re-wired a few more bits from the Meg to Laguna loom today. Alternator dash light, coolant temp sensor (Although im yet to get it reading on the dash), and I've cut back / re-taped up the conduit to get the ECU and fuse box further over into the NS wheel arch area.
Once the crazy lockdown has started to lift, I'm going to have a rummage around a few breakers yards under the bonnet of some Renaults, to find a nice housing / fuse box from something to fit into that wheel arch, and house all the Laguna electrics neatly.
And then I need to decide whether I'm going to run an airbox, or just an open style filter.
Didnt get chance to mess with the exhaust today, But will have a crack at that this weekend.
