Default Delco ignition changover Use a newer manual?

I will be updating my ignition to the newer style Delco unit tomorrow.
When and if I need to troubleshoot the system (late night middle of nowhere) will I need a newer manual that includes the newer Delco unit or can I use my current 1988 manual and troubleshooting trees??

Will this upgrade make any difference on my OTC 2000 scanner?

Just found one glitch in my current manuls troubleshooting tree that is different on the newer delco ignitions.On page 1 of Chart A-3 (Engine cranks but won't run). Next to number 4 the chart says to:

Remove 6 coil screws and tilt coil assymbly back.
Disconnect the affected coil'* CONTROL WIRE from the module.
Connect a test light between the common feed (Blue) and control wire for the coil being tested.
(The above refers to the older Magnavox Ignition)

O.K. can anybody tell me which of the pins on the Delco unit are the control wire and witch pin is the commen feed (Blue) wire.

This will be greatly appreciated if (when) I am out in the sticks and have trouble and need to pull out the manual.

Thanks

I'm not sure what pin is what on the Delco type vs the Magnavox, but if you keep your magnavox around, troubleshooting will be quite simple. Just swap in the old one and see if it takes care of the problem.

That won't narrow it down to whether it'* a coil or the module, but it'* a start at least.

Default coil

I'm keeping a spare Mag. and ICM in the trunk since I go stuck on the interstate last summer.
I bought a replacement at the wrecker. Saved the coil as mine was new, and put it on my old ICM which still worked but occasionally stalled and put the whole assembly in the trunk.
I think I had fixed it by just cleaning and tightening up on the connector.

JMFC is correct, if it'* ignition related, everything is the same, except the ICM and Coils, all you need is a spare that you know works, or another car you can drop your ICM and Coils in to insure operation. If you have narrowed it down to the ICM or Coils, if the car doesn't fire at all, it'* the ICM, if it sounds like it wants to, or you know there is ignition somwhere, try switching the coils around on the ICM. Often times that will fix that problem.

Personally, I wouldn't do that. But if you do, just start at the highest range and work your way down, so as not to fry your meter.
