ignition switch bad?
I was in the process of doing the DSII swap on my 86 F150 300 6 when i figured I should make sure it still ran. With the old harness still on (unplugged, as far as i remember) it started and ran fine. Halfway pulling the old harness off I tried again and got nothing. I was able to get the truck running by crossing the solenoid terminals. I replaced the solenoid and still get nothing. Could this be the ignition switch or did i screw up something from the old harness? What should I test first? Also, I'm not getting any blinkers or dash lights, except emission light, when the key is in the run position.

There is a red/blue-stripe wire that will get battery voltage with the key in START; this energizes the solenoid which crosses the fat cables together to feed power to the starter motor.
#5 on the diagram.
Make sure you have that voltage on that wire with the key in START; if not, could be a NSS (on auto trans) or clutch switch (on later years) or the ignition switch (but the problem is usually one of the others listed above).
