I just bought some fuel lubrication from Pettit and they sent me a special kit for becoming a new customer. It is labeled "Engine and Chassis Upgrade Grounding Kit." or something to that effect. Has anyone else installed one? Is it really something worth installing and why? If so, need some help in locating exactly where to connect everything. Specifically mentioned is a bracket where the factory strap is connected to the engine block. They mention this bracket and an empty threaded hole to re-connect with supplied bolt. What the bleep are they talking about. I guess I could ask them if no one has heard of this kit but I want an un-biased opinion if this thing is even worth installing.

My first visit to Pettit in '98 got me that same kit. Of course I installed it, it came highly recommended from the ones in the know.

But seriously, in your research about up keep on this car you should have found significant threads about upgrading/redoing all the ground wires on these animals.

Animals is right , rajee :P

I did a search and it yielded some results about the gredi kit and a few mentions here and there in the context of other subjects, but no specific mention about the Petitt kit. So I take it that it is worth installing. Now I just need to find out where this bracket and threaded hole is they are talking about on the engine block. I found the one mentioned on the shock tower for grounding to the chassis. I don't want to connect the thing wrong and blow up my whole electrical system or other such fool thing

To be honest, I've never had any electrical problems and don't want to create any. Its kinda difficult to follow where wires lead in the engine compartment. The diagram that comes with the kit isn't very good. Doesn't show the engine block hole or bracket location at all. Well I guess my next step is to call Petitt and see if they have a better diagram or can talk me thru it. Thanks for comments. I'll do some more search variations in this forum as well.

Well I did some more research on grounding and found many posts about people who are re-doing *all* their groundings over the whole vehicle. No specific mentions of the very simple Pettit upgrade which only involved 2 termination points. Anyway the jist of it is that Pettit supplies a small 2 ft cable of a very heavy unspecified AWG size with nice pre-attached terminals. The first step is easy. They say just connect the small cable to your neg battery terminal and run it over to a small threaded hole on the driver side shock tower, after carefully removing all the paint around the hole with sand paper (I used a Dremel tool). But then they instruct you to follow the factory cable that begins at the battery neg terminal and ends up connecting to the engine block via a small bracket. You are then to unscrew the small bolt holding the cable to this bracket, discard it and re-connect to an empty threaded hole located right below with a new small bolt and lock washer provided in the kit. I cannot locate the bracket they are talking about. I think it may be easier to see from below looking up so perhaps I will ask my mechanic to check it out using his lift the next time I have the car down there. Or perhaps will put it up on my ramps next oil or coolant change and take another look myself. In any case the first part is done so I know I have a good connection to the chassis. I just drove her and I think my oil gauge flakiness has dissappeared so perhaps this was the problem. Just thought I would share.

The bracket you are looking for is the factory lifting ring on the passenger side of the engine back by the firewall. You want to remove the ring.

This bracket is to the lower-left of the spark plugs just behind the AC compressor. It's greenish/olive in color and also serves to support one of the thick wiring harnesses coming from the driver side. This bundle of wires also includes the negative battery cable Pettit is referring to, which originates from the grounding point on the chassis/shock-tower just underneath the fuse box.

Thanks! That's exactly the info I was looking for. I'll check it out today.

I installed it. You need to screw it in an olive green bracket on the engine block. It just grounds it in a lower position than the stock place. Go from underneath the car, it's easier. I didn't feel much difference after installing it though.

Cool! Someone who has actually installed the same kit. Yeah, I'm skeptical that the 2nd part of the install is really going to do much. The first part of installing that little cable seems worthwhile since is actually makes a *new* connection as a backup at least. I'll have to get my baby up on ramps soon and at least look to see how much of a hassle this might be.

If you have no problems, the kit won't do anything for you.

I find it interesting that a couple of you guys interpreted Pettit's cryptic instructions to mean attachment at the left front of the engine as opposed to the right rear as I did. I attached where the emissions harness is grounded to the engine and the firewall to engine ground strap ties in. I didn't really see where removal of the lifting ring was going to make an improvement in ground potential, but the supplied bolt worked. Improved emissions harness grounding certainly helped on my FC. Its funny that the same technique (remove bracket - reattach strap with supplied bolt) works in two places. I have to ask what the removal of this forward bracket really does for ground potential just as I did for the lifting ring ? What would be better yet is to add a ground from that forward position to the frame. Pettit should have illustrated and explained this better, but it was free.

Silverstone

Yeah, Pettit probably wants you to call them so they can try to sell you more parts

Just wanted to say this thread is totally helpful, as I am a new FD owner, and a new customer of Pettit. I also got the grounding kit, but haven't really looked at it too much, so now I know what to expect. Thanks.
