New electrical kit?
So I've finally got my UIM off and am about to do all new vacuum lines. . . noticed a few have already been removed for me and am not quite sure how I had good boost up until now, but what the heck. As I'm taking off my manifild I notice how I have a slew of electrical lines that are extremely brittle. Some of the plugs were slightly damaged in removal also. . . they will all still work, but I would like to replace them. So my question. . . is there an electrical overhaul kit out there to replace all of these plugs and wires? I'm sure somebody has put one together, but I've looked at pettit's site and they don't have one. Anybody done this before??

Like how much stuff? I've already got my radiator, intercooler, AC condenser, AC compresser, PS pump, battery, all intake piping, and UIM off. There's not much else to take off. . . if there's ever a time to do it it's now, because a lot of these wires don't seem to be in good shape. So there's one main harness, I really think I should do this. Anybody have any good input on doing the job? Or any other aftermarket harnesses available?

If you can afford it, and are willing to get into the rat's nest and the injectors then go for it. There is a HIGH probability that the OMP lines will break if stock and more than 50K miles on them, so plan accordingly.
Unfortunately, there is no aftermarket harness.
Good luck,

When they get really old and brittle, they look like they're coffee stained. New OEM ones only run around $60 and they last for another 10 years. Very good thing to replace.
I agree with Mahjik as usual - replacing that wiring harness is a pretty big job, but if the old one is brittle and you intend to keep the car for a while it's money very well invested.
Also the FPD is a good idea, and so is getting the injectors serviced.

I've got the car apart, and plan on keeping it for a while, and continuing to learn as much as I can. OMP lines sound like a good idea, I'll see about getting the injectors serviced, and what about the FPD. . . what am I looing at here?

You can also add a little more piece of mind and go with the braided stainless OMP lines from a vendor of your choice. I think they are about $40 more than the stock lines ($100), last time I checked. As for the wiring harness, most of the plugs are found on other Mazda automobiles and some Ford products. For example: The alternator plug on the RX-7 is the same as a late model 4-cylinder 626. Most of these can be looked up under the "Common Connector List" found at your local Mazda dealer. They don't list connectors for the RX-7, but they do show pictures of the connectors and a little research is definitely cheaper than a new wiring harness.

The FPD needs to be replaced about every 5 years. If it gets too old it can leak fuel and start engine fires.
Mostly you can tell by the little piece of rubber coming out the top. If it's old and brittle then you should probably change it. Run a search - there are loads of discussions about it. The only bummer is Mazda wants over $100 for one.

I definitely recommend replacing the entire engine wiring harness at one shot (malloy has them on special for $730 right now) rather than hacking it up and replacing connectors.

Also, if you don't know if your car had the fuel-line and brake vaccuum recall/upgrade done to it, give Ray Crowe a call and he'll hook you up with the proper parts.
If you go with braided stainless-steel OMP lines, try and get ones with either a plastic sheath around them, OR make sure you don't have any moving/vibrating parts laying on explosed stainless-steel braid. It will eventually cut right through things . . .

Can anybody link a nice set of OMP lines that they would go with? I appreciate all the help guys. I'm definitely going to go with the new harness instead of the connectors, because it's not just the connectors that have a few broken pieces. . . these wires are really brittle and exposed in quite a few areas. My battery was already running dead for no reason, probably because of some of these issues. Any aftermarked ideas for the FPD that can upgrade quality for about the same cost? I'm going to post some pics of my project this afternoon so everybody can check it out. . . I've been taking lots of pics as I go and have the FSM that has been like a Bible. Thanks again for everybody's help!

As for the FPD, unless you are going with a complete aftermarket fuel system just replace the stock one with another stock one. If its lasted this long, another stock one should last just as long.

Just got home to check out some of these things on the car. The OMD lines look original, they're kinda brown and nasty lookin. . . ordered the stainless ones via the link. .. thanks. The FPD lines I'm not sure of, and after a few minutes of flipping through the FSM haven't found them yet. . . anybody have a good pic of them? Pettit did a lot of work to this car before I bought it, but didn't seem to replace some of the easy things.
I'm debating about the wiring now. After closer inspection the wires are pretty gummy, most of the brittleness seems to be in the sheaths. . . although some of the wires, like one to the airpump are just plain bad. . . don't know if I want to replace the bad ones, or all of them. Seems like a big job, but might not be as bad while I'm in there???

As for the harness, it's not that bad of a job, once you get into it. If you plan on keeping the car for a long time, you could also wrap the harness before installation to slow down the cooking process.
