Heater bypass - definitive wiring solution
#1
Hi all,
I was a little tired to see that single red cable hanging around my engine bay... Just didn't look right...!
So i spent some time looking for a better way of getting a switched lead...and i found it!
Remove the green relay; now remove the relay support (2 8mm bolts). Underneath the green relay there's a violet (maybe green/yellow on early cars) wire: that's it! With the help of a tap-in squeeze connector, connect a wire to that violet one (I chose yellow because it usually stands for "switched +").
Now terminate the new wire with an appropriate spade, put everything back togather and you're done! Simple, effective and clear.
Ciao

I disn't, beause i'm pretty sure that violet line is already protected....but you can add a small fuse if you feel safer...
The violet wire is 0,5, so it's ment to carry a very little amount of current (means safe to me...)

I tried this earlier today but my fans shut down. I put my old set up back (cross connect + and ground) and then they worked again.
Possibly that the connector hasn't cut through the purple wire but I think so. My yellow wire looks like the same size as yours.

Good job. The violet wire is Terminal X, it's fused, and this modification will only introduce a very small current draw, if any. It connects to the Climate Control Unit rear fan feedback signal input.

So this is working for you guys?
I haven't done anything to mine yet after the RS bypass duct was added and my heater works fine. I feel like I should even mess.
I was gonna do the wire mod from the coil, until I saw this, but it seems like I don't even need to do either.
