Wire set


Recommended Posts

I have a 94 Eldorado, same engine, so it's most likely the same setup as yours. I just did my plugs and wires a couple months ago. It's not hard or complicated really. Be sure you disconnect the battery first (negative terminal first for safety). It's much easier to get to the back plugs if you remove the strut cross bar and the Ignition Control Module (the thing the coil packs are attached to). There are 4 plastic wire harness clips that have to be unplugged from it (2 on each end), then there are 4 bolts to take it out (10mm if I remember right). 2 are in the front, 2 are in the back and are much easier to get to if you unplug the spark plug wires from the coils first. Be sure you mark or remember which plug wires go where on the coils. Then there is a plastic wire guard on the top-right of the engine. you have to remove that to get the wires out of it. When you put the new wires in be sure to put them back EXACTLY as the old ones came out including putting them in the retaining brackets. Also, when replacing the plastic wire guard, be sure that it isn't contacting the belt or pulley underneath it, which it shouldn't if it's on correctly.

If you have any specific questions, don't hesitate to ask. There are a lot of people on here who can offer you good advice.

Honestly I did the ones on my 96 eldorado and it was a cakewalk. 30 minutes tops, thats plugs and wires. It was much easier than I expected


Nice, clean, luxury= fine automobile

Ditto to cakewalk

Do one at a time, measuring the old ones against the new ones, listen for a positive SNAP, when you plug them up

It took me about 2 hours to change my plugs and wires, but I had 2 corroded plugs on my ICM to deal with, and I was working outside in 10 degree weather in the dark..... If the working conditions were better, it probably wouldn't have taken more than an hour. Aside from freezing my behind off, it was an easy job. My wires were pretty idiot-proof. The cylinder numbers were marked on them when I bought them.
