do8erman Posted April 24, 2014 Report Share Posted April 24, 2014 hi any help please 62 tr4 light switch has 5 spade connectors but only 3 wires connect problem is the wiring diagram shows the switch with numbers 1~8 but the switch has no numbers ?? the 2 blue wires are shown but not thick or thin which they are ? so where do they go ? also the dip switch has 1 and 2 on the outer spades and f on the middle one but no mention of that on the diagram . being colour blind hinders slightly many thanks in advance Quote Link to post Share on other sites
Lord Flashart Posted April 24, 2014 Report Share Posted April 24, 2014 If you have it, the Haynes manual has the pins on the diagram. Otherwise I can check later tonight for you what they are on mine. Sure someone else will chip in earlier though. Paul Quote Link to post Share on other sites

do8erman Posted April 25, 2014 Author Report Share Posted April 25, 2014 pfenlon thanks for the link but that's what I was looking at also looked at the tr3 diagram thinking as its an early car I may have that wiring instead but that was a no go / Paul i have a manual but not Haynes so if you can find the time to look at yours any info would be most welcome regards chris Quote Link to post Share on other sites
RAHTR4 Posted April 25, 2014 Report Share Posted April 25, 2014 Hi Chris, It sounds like you may have one of the "reproduction" switches. An original Lucas switches would be clearly marked with part numbers and the Lucar / spade connector numbers. Below is the back of an original switch, not a great photo, but I think you can just about make out the marking : Top left is 1. Next right is 4. Lower right is 6 Bottom left is 7. Bottom right is 8. Your wiring should be connected as follows : No. 4 - Brown / Blue ( N/U ) No. 7 - Red / Green ( R/G ) No. 8 - Blue ( U ) In respect of the brake light switch, I assume it the small type with three Lucar / spade connectors : Single left is common - connect Blue ( U ) single cable Top right - connect Blue / Red ( U/R ) single cable for Dipped Beam Bottom right - connect Blue / White ( U/W ) twin cable for High Beam and High Beam Warning Light Hope this helps.

do8erman Posted April 25, 2014 Author Report Share Posted April 25, 2014 hi Richard many thanks for this detailed reply I have removed the light switch and after a clean could see the numbers you show in the picture the only difference is the dip I have the large type (tr3 or early 4 ) spades all in a line but I am sure when the light switch is wired right the dip will be process of elimination . famous last words regards chris Quote Link to post Share on other sites
