Check out the schematics at Advance Auto Wire. They will probably be as
accurate as anything else around, including the Leyland "Brown Book". A link
appears below.

Subject: [TR] Confusion ...

I am doing some electrical work on the 1970 TR6, adding an electronic
tachometer.  First go around blew the bsacrifice resistorsb, I seemed to
have mis-wired the thing, as there are only three wires I am most ashamed.

			Red  power wire: to 12v, fused and switched by the
ignition switch.
			I found a good place on the lights relay box.   No

			Black wire: to ground, No Problem

			Yellow Trigger wire: to negative terminal on
distributor side.

				Problem:  My schematic shows the coil white
wire clearly on the - negative side.

				BUT  on my coil the white wire is connected
to the + plus side of the coil. I have the Pertronix Ignitor system
				(the one that just replaces the points).
The car runs great, never any start or run problems.

				So where do I connect the trigger wire, when
the instruction state connect the the - negative side of the
				coil for a negative ground car b& which the
TR6 is.

I really donbt want to blow up the tach again, that is getting to be

Ideas greatly appreciated.
