upgrading regulator

thanks Dana, a couple questions after reading: do I have to pull the distributor to check gap? or, can I pull plugs and turn engine over by hand to get each individual gap (states all 8)? I will have to wait until I put the rest of the wiring back together to do the check for the 'run' position on the ballast resistor. but, I still believe something is wrong with the way it is hooked up, because the blue wire with the yellow tracer is hooked on the same spade as the brown wire (on my car). as the diagram on page 10 shows, the start wire (yellow) should be on the opposite side of the ECU wire, which is not the case on mine. short explanation: starter relay to yellow to ignition switch to brown for the start position. brown is on the same spade as the blue wire with yellow tracer from the ECU. hence, I believe someone hooked it up wrong when they did the install. hence, post #13.
this particular diagram shows what I'm speaking of, and that the ECU wire is on the wrong spade connector on the ballast resistor

the car ran fine before I started this work, but do you think it may have damaged the ECU??? or was it able to run off of 8 volts?
in the diagram above, the blu/yel wire from the ECU is hooked with the brn "start" wire and the coil wire on my car.
I've learned a lot from reading everyone's posts in the threads, but not enough hands on to be confident. that's why I am asking the questions, to get the knowledge that comes from 'doing'. so, what do you all think about the ECU unit after being hooked up wrong?
