I'm planning on puttin a 99 4.6 SOHC in my 96 GT. I notice a couple problems already. I have the complete engine with harness and TB. Any advice would be appreciated.

1. The 99 has the coil on plug setup, can I use this with my cars wiring?

2. The fuel rail doesn't have a return, it has an electronic regulator or something on the left bank. What do I do with my original return line?

I was thinking of just using my 96 fuel rails, but then what will happen with the electronic regulator plug?

I could also use my 96 coils and harness, but I see some other differences in the wiring on the 99.

I think I'll quit now and let some of you experts tell me what's up.

Thanks a ton.

well for me when i switched over using 2001 heads and 2001 intake i kept everything together using my ignition and fuel system. just use your complete fuel system will bolt right up. and just use your original igntion should also bolt right but. and i believe you are also fine on the pulley setup i think in 2001 the changed the water pump. but you should be fine so just take all the fuel parts of the 1999 engine except the throttle bodie and then just use all your stock igntition parts just my 02
