Wiring?? confused smiley

I 'think' I may have found the "difference" between the wiring in my '67 Monza engine compartment and the drawings in the '67 Supplement! eye popping smiley

This picture shows the 'lump' covered by the 'wrapping material' on my Main Harness:

It appears that some PO had spliced in a piece of a '65 - '66 Harness at some point and NOT done it well!! angry smiley I would have been fired for doing that kind of a mess!!! sad smiley

One more step for the 'bucket list!'

Ouch! it looks like the "wrapping material" was electrical tape... makes for a slimy mess doesn't it? I'm curious though, are you going to rip all of the wiring out and start over with a new harness or try and repair the mess that is
there?

At this point I will try to repair what is there!

I need to get it back on the road (with the new Instrument Panel) before the "season" is over!!!

What's to "repair"???

Ohm it out... continuity correct.... low resistance.... good to go! Especially for a short time...Winter..

Sorry Matt,

I won't put my worst enemy on the road with a mess like this!

It is worse than it looks. I will post pictures as I go along.

I had decided to upgrade the harness connector which is why I started checking the harness. It was scraped off in a few places so I began taking it off to replace with heat-shrink tubing when I found the problem!

Not to hard to fix, just one more step.

Dale - Well that explains the difference between my observations and your "stock" 67 wiring. Not so stock.

I've seen a lot worse for splices. That said the 67 wiring was a safety improvement regarding electrical fires. Better to make it right and the next owner will be able to use the shop manual to trouble shoot.

Sadly few folks document "creative" wiring changes. Whenever I modify a friends wiring harness I make up diagrams for him to keep in his shop manuals for future reference.

I agree. I modified the wiring on my Harley for several good reasons, but I took a wall chart book of the wiring and added the changes so whoever ends up with it will (hopefully) understand.

I document all of my changes! drinking smiley

I don't want the next owner to be as confused as I was! eye popping smiley

I am 'modernizing' my Corvair so it will last another 50 years. The "next owner" will probably be my 5 year old grandson. He really likes it and I hope I am around to see him drive it! grinning smiley

That looks like the wiring in my '63 convertible. Maybe that's why it dies every once in a while...

I was under the dash of a 63 Spyder recently that had every wire coming out of the fuse block spliced like that. The owner bought the car more than 5 years ago and I don't think there's been any problems. I was glad electrical was not why I was under there and I could look away.

These splices are not too bad if done correctly.

Mine have extra 'bare wire' at both ends on a few, some don't seem to be crimped in the right place and they are not staggered so the 'bulge' ways quite large (4 layers of various 'wrappings' didn't help either).

I will probably start working on it this afternoon. Slow and steady will get the job done. At least it is not 90+ in the shade today and the Heat Index is down!

You know, it is funny how my friends and I were able to survive childhood without knowing about a "Heat Index" or "no action" days! eye rolling smiley

BTW, thanks to the suggestion about the "pin extractor set" from evilbay! I got mine yesterday and was able to remove the pins from my Instrument connector (only stabbed myself twice!).

I am now ready to install the new cable when it arrives! More on that after I get the Main Harness fixed!!!

So far, I have 5 of the 10 'splices' fixed (crimped, soldered, covered with new heat-shrink)! drinking smiley

Half way there, but I had to take a break, my back was not happy sitting in that position that long!!! sad smiley

It was interesting to see that whoever had done the last change had not paid much attention to wire color. It was OK in the Harness from the front to the splice area but after the splices I had TWO DARK GREEN wires (the 'correct' Dark Green wire spliced to a Dark Green wire AND the Light Green wire spliced to another Dark Green wire)! OOPS! confused smiley

Luckily I 'just happened' to have some Light Green wire on hand so that is solved! grinning smiley

Back to work!

Re: Wiring?? confused smiley Almost Done! eye rolling smiley

I thought I would finish my Main Harness 'repair' yesterday but came up with 'one more' item I need to fix!

I got 98% done and went to repair the last wire. This was the Pink "Ignition ON" wire from the Ignition Switch. For a '67 it should be (and was, from the Switch to the splice) a 12 gauge, Pink colored wire. AFTER the splice, it was a 20 gauge Pink colored wire!! eye popping smiley

That is something I don't have in stock, so it is off to the FLAPS to buy some wire! drinking smiley

I found two 'splices' that pulled apart easily, four with exposed copper, wrong colors spliced together, and last but not least the wrong gauge wires spliced together!

Fun!

That 20 gauge pink wire was a fusible link Dale - LOL.

Not surprised at all based on some of the kludges folks have brought to me to fix.

Years ago a fellow was building up custom car and was having "wiring" issues. I found opens and voltage losses. I started pulling on the crimp connectors and the wires just came out easy. I asked him why he didn't use a proper crimp tool. He said "I lost it, but pliers work fine". Well no they don't.

While I prefer soldered connections, sometimes a crimp connector is useful if it is done correctly. One example is the ballast resistor wire - it can't be soldered.
