D.U.I. Distributor Install
Since the instructions pretty much walk you through the steps quite well, I won't get too detailed and instead will mainly show pictures of what I've done. In short, you remove the current distributor, drop in the new distributor in the same orientation, run new wiring for the distributor, install newly gapped spark plugs, and run new spark plug wires.
Alrighty - time for some random-ish pictures.
I removed the factory split loom in order to remove the old ignition stuff. Once the loom was removed, I found a few factory duct tape splices...
To their benefit, the wires were crimped together...
I soldered up what I could and finished it up with heat-shrink tubing. Much better!
The following pictures are of the distributor installed and wires already ran. As seen in a previous post, the wires aren't for this truck. I re-ran them this previous weekend so they fit much better. This is also early in the install which is why the wires are all over the place.
I wired the relay in the following way (refer to the picture for the colors):
85: Ground (Blue)
30: Hot to Relay (Fused) (Red)
87: Hot to Distributor (Yellow which I spliced to Red)
86: Power from Key (Green)
I located the relay next to the battery. You can see where I grounded 85.
I took the hot (30) from the starter solenoid. You can see where I located the fuse as well. I think this keeps everything cleaner than having wires running off the battery.
Here you see where I spliced the yellow wire (87) with a red wire going to the distributor. Also, further below in the following picture, you can see where I spliced the green wire (86) with the factory wire that triggered the old coil (key on).
For reference, check out the following picture from this thread: http://www.jeepforum.com/forum/f8/du...supply-845594/
The hot wire (87) plugs into the distributor on the cap. This was while we were still in 'test phase'. I later installed the proper connectors on the wire.
And wouldn't you know it - I just now realized I don't have pictures of the final product. I also installed the Tachometer during this project. I'll try to snap some pictures of everything tonight!
I do, however, have a picture of everything I was able to remove from under the hood!
So far, she runs well. I haven't had a chance to really test it out and fiddle with the timing as there's been too much snow on the roads. Over the holidays, I'm sure I'll have it tuned up nicely.
Also, as a random question, does anyone know what this fuseable link goes to (sorry for the blurry picture)? It looks factory and the wire runs down under the truck. I haven't yet traced it but was curious...
Secondly, how does the factory under hood light work?
Here you can see a black wire running from it...
In this picture, the black wire continues on (draped over the heater core)...
Finally, the black wire splices into something (fuse?), the wire changes to red, then hooks directly to hot. Does the under hood light stay lit all the time?
That's all for now until I snap more pictures!
