sorry for the Andy-esque photo (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
Started to read the install manual for the Link fuel injection/ignition controller last night as well as the wiring for the Mallory CDI which will be used as well (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) Man, wiring is never fun, the hardest part I think will be laying everything out and figuring out how to run the wires so that it looks like a clean install....I'm still not sure if I'll be shrink tubing the entire harness or use the wire harness specific cloth-type tape.

Mike, that connector would be a 26 pin weather-pac connector. To drop the engine in my 911 you disconnect ONE connector.for the electrics

good idea !!!! here is a picture of the relay board I'm going to use (I think) the one pictured has the ground/12vdc switch/12vdc main power lines soldered to the board, I don't like that so I am looking for something I can more solder to the board so I can use terminals or the like......

Tim, what's that braided stuff made out of? Where do you get it?
Looks nice, and looks like it would do a good job in the anti-chafe dept. |

I must be doing something right.. finally.. I started using the stuff TimT is using back in Sept. of last year and never looked back. Once I saw it in the engine compartment of 996's/986's, I knew it would work for us. (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif)

James,
I bought rolls and rolls of it from the electronic supply place on Spring street in RWC about 4 blocks down from HPH. They have it in different colors and sizes. I combined it with heat shrink of the same color.. and coded where stuff was going for a easy to read wiring diagram for the car when I was done. B |

James, modern cars do not have engine bays open to direct water like ours do...That split in the corrugeted casing is not waterproof. Consider where water will end up when the engine bay is exposed rain...yes, inside the harness...Corrugated casing is not optimum or even appropriate for our cars engine bays. My wifes 5-series Bimmer has sealed harness even in the rear trunk, don't know about other modern cars. I have taken apart at leat 200 of our 914s harnesses...I see the kind of harsh conditions they are exposed to...and how the OEM harnesses have performed.
Now if its to be used in protected locations...I couldn't see a problem with that.... (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Same with the polyester braided sleeving guys, its not waterproof. While its great for abrasion resistance, it wont keep the dirt/fluids out from where it counts. I think heat resistance may be questoinable too, but I would have to check the products specs. Just MHO...YMMV...you are free to disagree.... |

Yes. I knew going in there was NO way the braided stuff would be waterproof (duh!).. but these are on cars that will only get "caught" in rain.
I also thought of it this way: If it is braided.. I stand a better chance of it drying out and having NO water sitting in the harness. I yank every piece of GM "wireloom" I can find from every 914 I see with it. Cheap shit that doesnt belong on a german built car (IMG:http://www.914world.com/bbs2/html/emoticons/barf.gif) B |

Ok...since this is a wiring discussion...where the hell do you order decent crimp connectors from? I am not looking for original porsche stuff, just good connectors...and I do have a "good crimper" just looking for good connectors to go with it.
Thanks, Tony |

The GM Weatherpak connectors come with crimp pins. They're available in 1-N pins. I used to think N was 12, but Tim showed N is much higher than that. You can get these connectors from several online stores. |

no rules, just wrong Group: Benefactors Posts: 2,321 Joined: 13-January 03 From: San Jose, CA Member No.: 141 |
Nylon braided harness covering can be bought in the south bay area from Halted in various sizes. Who will be the first to use it over their shrink-tube covered wiring harness (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) (actually that might not be a bad idea).
The stuff makes great Chinese finger puzzles if you have kids. |

Tony, I bought my uncrimped connectors from this guy: RS Autosport I know NAPA autoparts carries these connectors as well. Summit Racing "might" have them...... |

for the GM Weatherpack connectors, I added a little bit of potting compound to ensure a watertight fit (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)
yes, the little rubber gromments are backyards on this one...no big deal with the potting compound (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) Attached image(s)

Hey Mark, I got one of Mueller's laptops as well. Finally got my PCMCIA card to work in 95, and I just upgraded to 98. Seems to be working OK. If it's stable, then goes in my 802.11b card and we'll see how it flies... Nice Pics, BTW. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) I like those weather-pack connectors. I need to get some of 'em. Later, Tom |
