Turn signal fitting Lincoln Mark VIII

Good evening, I have a little problem with my 1997 Lincoln Mark VIII. Something to the history: the Lincoln had yellow turn signals and everything wonderful, however, during this conversion was built properly Murks: the brake light switch was simply cut through and led back to the brake lights, the cable of the brake light [Through the cable leads brake and flash light, since no brake light arrives – since cut – only a flash signal arrives] was then rear i The car flashes yellow and brakes red without flashing red. This led to the following m.M.n. serious problems, which met the requirement for yellow turn signals but has deactivated the following by far important things: – Tempomat does not push out at the brake, I found out when I drove on the highway at 130 km/h and had to brake. The car then gave full throttle, as it probably thought I was going up a mountain. Here – The ABS didn’t work anymore, but no error was shown, because there was no malfunction. The car doesn’t know that I’m braking because the cable is cut. – The Torque Lock Up didn’t go out while braking anymore, the gearbox turned down very funny. I was able to fix the problem temporarily, because I switched it all back to original. So the cut-out cable got back to it again. All the above problems were gone. Now, however, I would like to turn yellow again and did the following: The flashing light is picked up by the front turn signals, the brake light I led directly from the brake light switch to the bulbs and additionally into the module which should know that I press also on the brake. So far everything is ok, however, the turn signal is blinking now very fast. Since I actually have 0 idea I am now a bit unsich Is it right to assume that the brake/blink light cable that has been shut down now has to be replaced? I have heard that problems can also arise with the light module, this also applies to the year 1997 or concerns the more recent models in particular Ford Mustang? I have also added the schematics. I would be very pleased about suggestions!
