I'm putting a 2.8 V6 form an 86 Camaro in my 79 MGB and I need some help. I have everything but the O2 sensor wired up and one wire from the coil that I don't know where it needs to go. Its the black and white wire from the gray plug. When I try to crank it the engine turns over fine but the engine will not start. Once the engine fired on about 3 cylinders but that was it. I checked the diagnostics on the computer and it kept flashing the 12 code and that was it. Any thoughts at all? and to see pics go to my webpage: http://bellsouthpwp.net/a/d/adam90009/v6_conversion.htm
Thanks - Adam Housley

edit: By the way this is my first engine swap and I'm 16.

 

Congrats on the swap

Any pics of the black & white wire w/the grey connector? And which coil wire????

 

here are two pictures, It is from the light colored lug on th top of the coil and the 2nd one shows what the conector looks like.

it looks like the ESTC connector, but I no longer have it on what's left of the 2.8 harness.
