1995 BMW S-50 Motor going in a 1969 TR6

[BMWTR6]

Hi I recently completed my TR6 Chassis http://www.318ti.org/forum/attachmen...1&d=1455076988 & decided to buy a wrecked 1995 BMW M3. The car is scrap! I will be selling off all the M3 stuff it's got cool seats http://www.318ti.org/forum/attachmen...1&d=1455077115 . The S-50's pan was shattered in the accident, I replaced the pan, pick-up tube & windage tray, put oil in it and it fired right up, sounds great!. Before I pull the engine, I need to figure out what will need to come with it into the TR6. The 5 speed Getrag tranny will come with, as well as the OBD1 system, and that is where I am a little foggy.. well maybe more than a little. Dave from the TR6 forum States. "Believe it or not, the BMW harness plug has only four wires to be connected. One for power, one for the fuel pump, one for ground and one off the alternator. The simple OBDI computer controls all engine parameters and has only one Oxygen sensor. I'm hoping to find a little clarity here. & offer up some goodies to the BMW Boys & Girls...
Not mine but well done..http://www.318ti.org/forum/attachmen...1&d=1455075515.
Any interest in this adaptation / modification would be appreciated.
