Not many rules really, this board being aimed at technical issues, it shouldn't fall foul (hopefully) of some of the more personal issues that can affect forums.

Rule 1 - Is that you need to think very carefully before posting anything technical or asking anything technical relating to the security system of the car - See 'Security Issues' sticky for more info.

Rule 2 - We (MGF Register) do not support copyright infringement and therefore references to CD ROM, PDF versions or paper copies of the workshop manual (for instance) should not be posted on the forum. We don't want to get into trouble and we'd rather sell you a genuine hard copy through our Regalia shop anyway! :)

Wiring loom already in place - but you'll need a switch and a relay.

Is yours a pre-2003 TF? Wiring system altered significantly with the introduction of the Pektron Security Control Unit (round-shaped key 'plipper')

Hi Rob

Hard top purchased from me. (nearside wing, if you remember)
They may need some better description. I looked for the window end of the loom under the carpet on the parcel shelf but could not find the connector or loom. Where have they hidden it?

Hope all is going well with Project Shed!

Regards
Mike Sherwood

I bet the plug is well hidden under the parcel shelf carpet/sound deadening - and may even be found somewhere down the front of the bulkhead panel!

As Rob says the wiring loom and plug will be there it's just a matter of looking in the corner beside the seat belt reel behind the passenger's seat. Once found connect the heated rear window wires to the loom plug. Next is the switch and relay. First have a look in your handbook to see where the heated rear window switch should be in your car because they are keyed (normally left of centre). You can just see it in this picture next to the rear fog light switch -

Take off the passengers footwell panel (the one with the light on it); put your hand in behind the switches and push the appropriate blank out (don't worry if the next switch comes out as well). The wires for the switch are plugged into the back of the blank. There isn't much wire so I find it helps if you pull the blank and wires out and turn them through 90° so they don't slip back through the hole. Unplug blank and plug switch in it's place and push everything back into the dash and replace panel. Next is the relay. Under the dash to the right of the steering wheel you will see a panel that covers the fuse panel. It has two catches that you use a coin to open - you just need to turn them 90°, they do not screw out. The fuse panel changed around 2003. Depending on which panel you have you will either need to fit a large (normally yellow) relay to the bottom of three sockets which is empty on the right of the board. If it's the later board then you will need to fit a smaller black with a green stripe relay into the second from the top on the left bank of sockets which should be empty. Fit panel cover and it's time to see if it works. THE ENGINE MUST BE RUNNING and then press the switch and the light should come on. Next do some heavy breathing in the back window and you should see it clearing.
