Walter, you've pretty much got it. Your 4 relay diagram works like the one that Ken has, but the downside is the pilots won't act the same way as originally intended with separate rear turn and stop circuits. Your 2 relay system is the same as Jerry drew up, but the relay transition is the only time that the rear bulb would be off (very short.) The transition is ON/ON. Jerry is proposing adding a resistor in series with the diode from the switch, which would make the bulb dimmer when the flash happens, so the rear light would be bright-dim with the turn signal with brakes and dim-off with the turn signal only. There's no need to do anything to the 700 since you're tying them back together outside the switch anyway. The pilots in the 700 would work exactly like originally intended, and would be the best solution to the issue.
