To check if you have the wiring loom installed to fit electric rear windows you need to remove this plug, which is located between the front and rear doors (both doors need to be open to remove it)
Pull the seal out from the rear most facing bung (it has the wiring running to the door). Disconnect the connector, the loom in the door (with manual windows) has this connector and pin-outs:
If the other end of the connector (from the car loom) is the same as this, you DONT have the wiring for electric windows. However, if the plug is full of pins (all but 2 pins were used on my car loom plug) then you do. Its that simple to check beforehand.
I did it blind, until removing the plug to connect the loom - I was prepared to re-wire the car though. Hopefully the ST I'm breaking will have the loom as well, so I can trace it back, and possibly either make the looms for other people, and at least find out where it all goes.
Hope this helps you all considering doing the rear electric window conversion. I'll write a how-to guide up this afternoon hopefully and put it all in there.
To do the conversion you need:
- Both rear electric regulators
- both rear electric door looms
- both door switches to use windows in rear
- the 4 switch electric gear surround buttons
- 10x rivets to re-rivet the regulators in place
- some tie-wraps and insulation tape
- 2x 25mm bungs to cover the holes from the winders
There might be more, thats all I can remember for now... I'll do a how-to guide later and put it all in there.
