Okay when I started this engine conversion (Before I entered the trade) I basically got all the wires coming out of the firewall leading to the ECU/TCU, and ripped everything out, leaving about 9 bare wires coming from the dash, resting in my passenger footwell, as everything else was engine/trans related.

Now, I have no demister (relays dont click) or heater fan. I know these two relays sit next to each other, Just wondering before I start ripping apart the interior (moreso) is there anything I should look for. I'm thinking I have the two 12V feeds cut off (or the earths) that go to a connector just near the battery.

Can anyone confirm the power for these relays comes from that (10 pin?) connector just behind the battery?
The loom will all eventually be ripped out in favor of the Diamante loom but for now I need it back. Any heads up would be great.

Lesson learnt, ONLY cut the wires coming from the firewall going to the engine and transmission, not the WHOLE loom :P

As per my PM.

On another note - never cut wires....unless you're damn sure you know what they are.

As I dont have knowledge of Magna electrics, its hard to say what wire is what - only advice is to read the wiring schematics and wiring diagrams and start the long process of backtracing wires.
