    Working on my 89 Jimmy today and let me tell you that some GM engineers need to get their head out of their but. Anyhow I went to put plug wires on but I can't get the old ones out from behind the head. I took the bolt out of the bracket on top that the vaccum hose is connected to for the brakes, then I crawl under and loosen the nut on the bottom of the bracket (the bracket just slides over a stud, right) but can't find what else is holding it in place. Can't see anything because the cruise and all the other BS in the way. So will I have to take all that off or am I missing something here. I have never seen such BS for spark plug wire routing in my life. At least I can figure out why they are the origional wires with a 150,000 miles on them. I guess the last owner didn't want to mess with it. Thanks.

    Why don't you just cut the old wires? [​IMG] You are replacing them right?

    Re: What am I missing here.

    I thought of that but when I unhooked them from the dist cap they will not slide from the clamp on the back side. I even had the valve cover off to replace the gasket and still couldn't see a thing.

    I always thought those brackets were attached to the bellhousing bolts, mine is an 81 though so it may be different.

    The only nut I found was on the stud in the back of the head. A pain in the a$$ to get to when laying on the ground.

    I just pry open the plastic "lid" that holds the wires into their clips. It will probably just break off because the plastic gets brittle from all the heat over the years. Yank the wires out of the clips and install the new ones. Never had to use a wrench to change plug wires. [​IMG]

    Re: What am I missing here.

    Ya, those clips do have a hinged top on them.. Try sliding the top of the plastic bracket sideways....

    Dont you just love them engineers? I would love to meet a few one day in a dark alley! ;)

    Unfortinatly these are differant then the older type. They run between the valve cover and firewall and the clips are on the backside of the bracket facing the firewall. You can't even see the clip from on top. I think I found the fix though. I just called Summit racing and ordered a new wire loom kit that will run them over the valve cover. Once I get them I will just cut the old wires and try to yank them out and reroute the new ones so I won't have to worry about it any more. Thanks for the help though.

    Wayne, I replaced mine a couple of years ago and I think I ended up cutting them to get them out. I ran the new ones a different route.

    GOT ROCKS?

    Wayne, you did exactly what I'm gonna do when I change wires. You're talking about that kit for centerbolt valve covers by Made For You, right?

    Automotive engineers aren't the only ones who design thinks to be maintenance-hostile. A LOT of aircraft are a b!tc# to work on because the aerospace engineers never considered the maintenance requirements... I'm fond of saying that all aerospace engineers should be aircraft mechanics for 2 years before they're allowed to design airplanes, so they know what it's like.

    Yep! They're on my '87 TPI 383, my '91 4.3 and 'my 94 350. It ain't easy to get back there but I've never had to unbolt the bracket itself.

    I think I know what bracket you are talking about. I just broke mine off and used some parts store wire looms, but they are gone now...i rerouted the wires not using the factory stuff.

    Ya jarhead those are the ones I ordered. Even got them in blue to match the truck. I think it was $50 well spent to not have the headache again. I just wish they were as cheap as the last ones I bought for my 350 in my 73 p-up.

    So that's why my spark plug wires where all over the place when I bought my '90 and none were in the clips! Someone did me a favor and I didn't even know it.
