100-4 flasher unit buggin' me

The small cylindrical flasher unit has three terminals. My workshop manual schematic tells me only two are connected to wires and that they go to the flasher relay. The flasher lamp on the dash draws its power from another source (circuit) with different colored wires. Does anyone have information that is contrary to that? Something I've read indicated the third terminal should wire directly to the dash turn indicator lamp. Which is it?
 
BN1 or BN2? I just wired the flasher for a BN2 and all three terminals were used and, IIRC, the 'light green,' unwrapped wire went to the dash indicator light (might be the power source). If you have the shop manual for the 100s there are two schematics, and one is for 'later cars.'
 
I have the factory service manual for the 100-4 BN-1, which is my car. It shows a green/brown wire from the "l" post on the flasher to the #1 terminal on the flasher relay and a green wire from the "b" post to the 35 amp fuse at the fuse block;then on to the trafficator and splits off to the stop lamp switch. Nothing on the "p" post. When my flasher light was working, it had a green/white wire to #6 terminal on the relay and on to the right front turn light. The other wire was green/red to the #2 terminal on the relay and on to the left front turn light. These wires came out of the loom and in the past they worked. I know this is complicated but I'm baffled on why the manual shows only two wires. Bob thanks for your input. Any other hints would be appreciated. Any BN-1 guys willing to look at your car for some input?
