Oh joy....engine wiring harness fun begins, starting to wire up the LINK fuel inject Options

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.

To lay everything out, mount all of the components first in their final positions. Lay the harness out wire by wire, so you can get each to exactly the length required. Use zip ties to temporarily bundle wiring to keep it neat.

Don't use heat shrink on the whole harness. Use the corrogated plastic split tubing. This stuff is specifically made for this, and you can easily get back in later without unravelling a zillion miles of tape, or cutting into the heatshrink and hoping you don't cut into wire insulation. Use heat shrink over connectors where the wires feed in, both as a waterproofing and strain relief. Sometimes you have to put layers of heat shrink on to get a good seal. A big piece that will fit over a connector usually won't shrink down to the wire bundle, so use a smaller piece over the shrunk bigger piece, and repeat as necessary.

After you get the whole harness done and operating properly, re-zip-tie as necessary so "branches" collapse into natural "trunks". Wrap the trunks in the split tubing.

Use good connectors. If you're crimping (my preference in a high vibration environment), buy a good crimp tool, one of the $40-50 jobs that properly "fold" the crimp connector around and into the wire. If you use the hardware store insulated connectors with the crimp tool that just crushes the insulation and the crimp, you're going to end up with something that will be flaky to start with, and will give endless trouble. If you REALLY want to be anal, use a small bit of heat shrink around each wire and the crimp connectors. Don't use spade or bullet connectors if you can avoid it. Use only-goes-together-one-way multi-pin connectors with crimp-on pins where possible.
