alan pettit Posted June 10, 2012 Share Posted June 10, 2012 can anyone help with these rather silly questions.. sorry but im building the car from boxes of parts so not quite sure.the rear overrider wires must connect with the back lights wiring. how are they routed? there is a hole in the rear inner wing ,is this what i pass them through?Also the lights in general ,the only light switch seems to a rheostat for the instruments.is this also the main light switch? mine may be a dud switch as it dosent seem to pull out just turn as a rheostat. thank you Quote Link to comment Share on other sites More sharing options...
Keith Posted June 10, 2012 Share Posted June 10, 2012 Alan,On mine the wires for the number plate lights go through the holes in the inner wings and them through the bumper iron holes in the rear valance. I can be certain that that is correct as the car has been rebuilt.The master light switch is the left hand switch on the column, do you have the correct wiring diagram? The works manual only shows the TR4 diagram which is different, the correct one can be found in the driver's manual i.e. the little glovebox book.Keith Quote Link to comment Share on other sites More sharing options...
Hogie Posted June 11, 2012 Share Posted June 11, 2012 Hi Alan, as Keith has said the number plate lights wiring runs along the overridder stabiliser then through the rear valance bumper iron hole then up to the inner wing wiring access hole - use plenty of plastic ties to keep in place.Try and keep any connectors inside the boot area as water from the wheels will get into and annoy the leccy bits if possible.Again the light switch is as keith states - spot on.The Haynes manual has the TR4A circuit diagram but not the 4.Roger Quote Link to comment Share on other sites More sharing options...

Hogie Posted June 12, 2012 Share Posted June 12, 2012 Hi Alan, off at top, side, mains. Take it slow and think about each connection. You don't want to melt the loom.Roger Quote Link to comment Share on other sites More sharing options...

alan pettit Posted June 28, 2012 Author Share Posted June 28, 2012 thanks for the help. last night got horn,fan and most of the lights working, no sidelights at front or indicators at front yet but the fuse box needs a good clean to make contacts better so i live in hope !. Also got wiper working but they seem a bit slow, almost sticking, is this a sympton of lack of use? The earth contact is very good. Quote Link to comment Share on other sites More sharing options...
Hogie Posted July 6, 2012 Share Posted July 6, 2012 Hi Alan, when testing the wipers ensure that either the windscreen is wet or the blades are lifted away from the glass.Roger Quote Link to comment Share on other sites More sharing options...
