I need to know where the plug wires go.from spark plug to distibuter cap on a 1986 4.1 coupe deville(cad.)


FIRING ORDERS NOTE: 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.

If i change from a v6 to a v8 on my 93 mc do i have to swap out the computer?


No, they use the same computer. But the prom chips in the computer are different. It will run fine on the 4.3 chip but it will run better with the V8 chip. After you switch it, I would order a performance V8 chip for it.
