Ihave a 95 vette and I really need a detailed description of how to change the plug wires on the drivers side. I have looked at it several times and now
I feel really stupid. I have no idea how to change them. Someone please help me to not feel soooooooo stupid. I have look in my manual, (Bought at Advance Auto) and it shows nothing!!!!!!!!

 

They are not difficult. They just take time. Buy a six-pack and about every hour stop and have a cold one.

Start by removing the MAF sensor and air duct hose between the air filter assembly and the throttle body.

Remove serpentine belt.

Remove belt tensioner.

Remove alternator.

Loosen p.s. pump.

Now, just take your time and remove one wire at a time.

Reinstall all the parts you removed.

Good luck.

 

I do mine without removing the alternator or PS pump. Some guys remove the wheelwell too. Not me. I remove the ASR and just swing it up onto the windsheld so that it's out of the way. I can then get to all the plugs and wires. You do have to remove the serpentine belt and tensioner though. And just feed one wire thru at a time. Oh and seeing how this is your first time. You may want a 12 pack..

 

I just did them on my '95 a couple of weeks ago. There's a tech tip on this with some photos that helped a little...it has a photo showing the Opti, and which wires go where.

I took off the serpentine belt and the wheel-well access panel, put the front-end up on jackstands, then from underneath took off each wire starting at the bottom of the opti. I extracted each wire, replaced it with the new wire on the plug-end, then draped it over the engine. Once the entire bank was done, I threaded the wires back down to the Opti in the reverse order...so that the last one I took off (at the top of driver-side bank on the Opti...bit of PITA) was the first one back on.

Unless you have small hands, it's pretty tough to get enough grip on the wire boots on the Opti-end to get them off/on...particularly the top two. I laid cross-wise under the car with my feet out the passenger side, and used a couple fingers on one hand on one side of the boot, then reached around the front crossmember so I could get a couple fingers from the other hand on it...worked great.

Project took a little over an hour, and there was plenty of room, even using MSD 8.5mm wires.

Hope that helps!

 

On my '94 LT1, I did not remove the alternator, and this is the first time I've heard of anyone who did.

I did unbolt the ASR mounting bracketry from the frame (but didn't disconnect or fully remove the ASR -- just loosened it so that I could move it out of the way as required).

I also found it very helpful to unbolt the power steering pump so that I could move it forward around 1/2 inch to facilitate sneaking the wires out/in behind the pump.

I also removed the serp belt and tensioner to gain access to the Opti end of the wires.

Raising the front of the car to a more comfortable working height definitely helps. Removing the center wheel well panel helped too, both with seeing what needed to be done, and with actually doing it.

Use dielectric grease in the plug wire boots at both ends. Make sure the wires are fully seated on the plugs and Opti towers, and be sure to burp any trapped air out of the boots so that the air doesn't push the boots back off later.

It's a PITA, but with patience, it can be done. Route the new wires exactly as the old wires were, assuming they are original. Be sure to keep the wires clear of anything that is sharp, moves, or gets hot.

Good luck.

Be well,

If you have the option to put the car on jack stands you can do it from under the car. You can see the back of the opti from under the car! It is possiable, I have done it
