86 V6 - V8 conversion help (mainly wiring related)

[EazyE-CPT]

The car was a V6, now I got the V8 engine in the car(86 HO) but the engine isn't getting spark and the coil/ignition module are fine. The only thing that I'm sure isn't hooked up right is the alternator. Theres 3 wires coming from the back of the alternator, and I only have 2 hooked up becuase there only 2 alternator wires coming from the front wiring harness. On the alt side of things, one wire is large, the other 2 are small. The big one is hooked up correctly. The small one thats hooked up appears to be going to the silver box by the coil.

Where should the other wire coming from the alternator be hooked up?


The HO engine came from a Mark VII if that makes any difference.



Also, anyone know where the smog pump vacuum line hooks up? Its really long and reaches kind of towards the back of the engine...Theres no more vacuum ports open for it to hook up to. Woudl it be alright if I just plugged it off?

Also, where does the MAP sensor vaccum go? I think its the back of the intake, but I dont think theres any spots open for it. Is it alright if I dont have a vacuum hooked up to the MAP sensor? I know you can do that with Mass Air, but Im not sure about Speed Density....


Just one more Q . Theres a large round plug on the pasenger side of the front wiring harness that doesn't have anyhting to goto. Would that have anyhting to do with the engine not getting spark? Does it have to be hooked up?

I have a feeling Im just gonna have to end up buying a V8 front wiring harness
