The ignition switch in my 1970 TR6 has gone belly up; the internal spring no
longer returns the key to "run" after starting. The switch has 7 male
connectors on the rear and one rather strange spade connector on the right
side. The rear connectors on the back are arranged:
1. Brown/White (heavy wire) 5. White/Red (heavy wire
2. Brown/White (heavy wire) 6. Black
3. Double White 7. Empty
4. Single White
The wire to the side of the switch housing is Black/Green
The switch for the 1970 is NLA so I can bought the switch housing for a later
car (TRF 216446 / Moss 667840) but it has only five male connectors. So, on
advice bought a plug (electrical portion of the ignition switch assembly) for
a later car (TRF LU39911) to replace the electrical portion of the switch
assembly with the new plug, which I was told had 8 wires. Being the original
switch had 8 wires I went for it. Upon arrival I noted LU39911had 8
soldered connections on the rear with 8 wires running into a harness that
ends in no less than 16 wires running into 15 wire terminals (5 female spade
connectors and two lucor connectors).
Here's the dilemma - there is only one large brown wire coming off the
LU39911 unit, somewhere in the harness it splits into 2 wires but I'm afraid
combining the two existing wires into one could create (heat/melting/fire)
problems. Has anyone ever faced and solved this before or does anyone have a
proper 1970 switch for sale?
I'm thinking of changing to the dash mounted switch of 1969 but don't know
how many connectors that year's switch had.
Thanks for your help!
