To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

I need to see a picture of vacuum diagrams for the vacuum lines that are reach from the "radio cavity" the blue one is disconnected and I want to reconnect it. the vehicle is 1990 cadillac sedan...


I couldn't find a diagram of those vacuum connections. If only one line is disconnected then look for an open hose nipple on the AC control assembly and that should be where it goes. Those vac lines supply actuators which move diverters in the duct system that activate the different climate control system modes.

Access to odd numbered spark plugs on North-Star V8


To gain access you have to remove the ignition coil pack. There are only 4 10mm bolts holding it on. Also remove the cross over to have more room.
