I need to know which wires to conn. to brain box from ing

Are you using the stock ignition? When I put the new Duraspark on my V8 I had to just trying every wire till I got it figured out. If you are using this type(Duraspark) ign......the start circuit has to have a hot wire all thru the start cycle.Some of Fords switches did not have a hot wire when the switch was turned to the start position. I hope this helps some.

thanks for your help.
one more ?
did u use factory comp. or ford brain box???

if you are using the factory brain box the red wire comming out of the brain box has to be hot when the ignition is on. the 4 prog clip just plugs into the motor part of the harness. and the wite wire on the 2 prog clip goes to the starter wire. but you can leave it unhooked if you want it makes no difference. your motor will run with this set up as long as you complete the rest of the harness.

I use the aftermarket Ford-type box.....BLUE.

yeah, I have the one with the blue clip on my 351M also. I think that box will run any ignition.
