ok, I will say this more time..the HARNESS for EFI is seperate...unplug the EFI stull and roll on...just did a 98....simple if you can't get past this give up..

I got that part. I'm concerned with the distributor. Just need to get thunderbolt iv parts and slap it in?

i would assume computer controlled ignition wouldn't work without the computer. some type of stand-alone ignition would be necessary.

When I removed the EFi from my motor, I simply unbolted the lower manifold and and removed all the wiring connections going to the main harness. I was going to use the stock distributor and stuff but ended up not using it and used all MSD ignition items. I think there are 2 or 3 plugs that have nothing going to them that I bundled together and ty wrapped them neatly together out of the way. No need for a new harness just use the one you have.
