For the past 17 years I've been running my engine harness from the connector across the firewall like it's supposed to be.
Then, it gets sketchy. I go down the passenger side of the engine, down the front, and then back to the starter. There's nothing holding it in place and nothing protecting it from heat except some tape and wire loom. It's basically draped.
It was so long ago that I took out the 300, I can't remember what was used to secure it?
The harness is not in good shape, old and insulation poor. I need to get this worked out - and for anyone curious or can't remember my situation - it's A SBC now.

Didja consider an OEM Buick wire tray? Its clean and sanitary. Heres some pics including the original fireball V6 install if that helps. I also wrapped my wires in that black slit accordion stuff. Bill

What you need is a Buick big-block! . . . . . . .(http://www.canebas.org/WeatherCat/Forum_support_documents/Custom_emoticons/Laughing_LOL.gif)
I'm sure Bill agrees! . . . :hello2:
Once you have the big-block in, getting the wiring straightened out is just a matter of details . . . . . (http://www.canebas.org/WeatherCat/Forum_support_documents/Custom_emoticons/can_of_worms_emoticon.jpg)

It bolts to a bellhousing bolt and holds everything away from the heat. Many an old car has burned up thanks to the original wiring or positive cable shorting to ground.

Yeah schlep, just found those last night looking around. But is the routing straight down the back of the engine for those wires? And then the rest go over the valve cover?

Dear Bill, Chuck, Iain, Dan, and mid-60s Buick electricians,

Alright, alright, I can be more constructive after all. I do have some pictures of Biquette's original 300 cid V-8 while she was getting repaired from the accident of November 2010. Alas, I only have two pictures of the driver's side of the engine bay. Here is one:

Here is the other:

On the passenger side, at least the wiring related to the lights is routed over the inner fender. I don't see any other wiring in the pictures, but perhaps the rest of the 65GS.com crowd can offer some additional observations.
I hope that's a little help!
Cheers, Edouard :occasion14:

Here are some pictures from my 65 Skylark parts car that had a 300 4V engine. The engine had been removed before I bought it, but the wiring harnesses are still in place.
Hope this helps......

Have done a lot of sailing with my Dad as a younger man, I normally think in terms of port and starboard. Of course those darn land lubbers don't understand. So when I post I try to translate port and starboard to driver's side and passenger side. Sometimes I do that too quickly! Worse still, driver's side and passenger side really doesn't work. In England and other places driver's and passenger's side are reversed. So I repeat - darn land lubbers!! . . .

So were you sailing in Europe? The lateral buoy system here is Red Right Returning from seaward. In europe is green, or opposite. Sooo. You just LEFT PORT, the red navigation lights are on the left and just to make it simple,hiccup, PORT WINE is RED. Dont even get into Timid Virgins Make Dull Companions LOL... bill

Ok.....crazy people.
Got another question here: Anyone used that sleeve wiring protector stuff? It's fiberglass. Available on amazon and who knows where else.
And thanks for pics guys! Does help.

I've used it at my workplace to insulate bare wire at high temperatures, 250*C/ 480*F. I don't know what the thermal insulating properties are, we just use it where conventional plastic-based insulation would melt.
For auto use, it'll get dirty when used underhood. And you'll have to thread wire thru it, so if there are plugs/connectors being used, it'll be tough to install. You can increase the diameter a little, maybe 2x, of it by bunching it up (push ends together to make it shorter).

Dear Iain, Walt, and mid-60s Buick caregivers,
. . . . .
Got another question here: Anyone used that sleeve wiring protector stuff? It's fiberglass.
. . . . .
As it turns out, Greg and the gang at Orinda Classic Car used the fiberglass wiring protectors extensively when they upgraded Biquette to the FAST Sportsman EFI system. Here is an example around the ignition coil:
(https://photos.smugmug.com/Biquette/Drive-Train-makeover/Misc-engine-bay-photos/i-nPqmtCC/0/8fe8e278/XL/Wiring%20to%20Igntion%20coil-XL.jpg) (https://canebas.smugmug.com/Biquette/Drive-Train-makeover/Misc-engine-bay-photos/i-nPqmtCC/A)
Here is an example on the firewall with the wiring that in part connects the fuel pressure sensor to the ECU:
(https://photos.smugmug.com/Biquette/Drive-Train-makeover/Misc-engine-bay-photos/i-xhBd8pH/0/e6d12c8e/XL/Wiring%20to%20fuel%20pressure%20sensor-XL.jpg) (https://canebas.smugmug.com/Biquette/Drive-Train-makeover/Misc-engine-bay-photos/i-xhBd8pH/A)
They also used plastic conduit for larger bundles.
Here is one more example of wiring going from the driver's side to the passenger side over the radiator:
(https://photos.smugmug.com/Biquette/Drive-Train-makeover/Misc-engine-bay-photos/i-pVP8HJW/0/4ed55620/XL/Wiring%20to%20starboard%20lights-XL.jpg) (https://canebas.smugmug.com/Biquette/Drive-Train-makeover/Misc-engine-bay-photos/i-pVP8HJW/A)
So these sort of wiring protection are suitable for automotive use at least if you buy the products intended for that purpose.
I hope that's some additional help!
Cheers, Edouard :occasion14:

Some of y'all have some pretty engine compartments... jealous. :crybaby2:
Now, got a question about the positive battery cable. Looking on rockauto, those available in that length don't come with the starter 'lug'. Is it acceptable to bend the tab that's commonly used of those? They are of good quality, either Standard or ACDelco.
_______
I see on the other thread about battery cables for the GS that they ran the positive to switch. Why? Why wouldn't use just run the cable straight to the starter?
-
They are just crazy Buick guys who overlooked that little ?SBC? in your first post. So, to answer your question your cable will go all the way from the battery tray to the starter solenoid. You can use the sleeve to route the small purple wire and any other wire(they may not be necessary if you are not using points)...the sleeve holds them away from any heat.The starter end should look like this one

Yup! That works! That is much better suited for automotive use than the product I'm accustomed to. They did a real nice jog with it! :thumbsup:

Dear Iain, Dan, Walt, and mid-60s Buick caregivers,

Both you and Ruthy have to be a little patient. Biquette has been in our family 51 years! After all the abuse she went through as a our family wagon, she deserved to be dressed up! I hope by the time you've owned Ruthy 40+ years you'll be able to give her the same kind of love! :love4:
Cheers, Edouard :occasion14:
-
Patience is a virtue..I know.
Schlep, none of the aftermarket cables I'm looking at have that fitting on the starter end. The one I'm running right now is just the same. It's newer, unlike the original harness. I guess when the time comes to get down n dirty I'll find out what sort of condition it is in.
-
You COULD just bend that little 90 into the end. That OEM piece has a little tab that locks the terminal into a groove so it can not touch the two other terminals. Sometimes I just find a good used original terminal and solder it on a new cable or whatever you already have.

New versus old engine harness

Dear Iain and mid-60s Buick caregivers,

Not so fast! Who supplied the new engine harness? Is this a commercial part or did you have somebody build one for you? It does look very nice but . . . . . curious minds would like to know!

Seriously, I know you were able to put a small block Chevy engine into Ruthy, but I have no idea how that effected the wiring harness. All the Chevy components hook up to the Buick connectors without any adapting?
Cheers, Edouard :occasion14:

Yes Edouard, I don't claim to know everything, but small block for small block. Everything was plug and play. And, before I even used the old generator (not alternator). A better wire was added when I upgraded to HEI. Everything else is the same.
:overthetop: The 'he' was myself... Maybe I should say 'us' ? :thumbsup:
-
Finally got this harness installed. New positive battery cable, too.
Plug-n-play, no mods needed. Some wires were not used.

Glad to hear that Ruthy is feeling healthy once more! I do hope you'll be posting some pictures soon! (http://www.canebas.org/WeatherCat/Forum_support_documents/Custom_emoticons/kodak.gif)
Some wires were not used.
(http://www.canebas.org/WeatherCat/Forum_support_documents/Custom_emoticons/wink_smile_triangle.gif) . . . . . Those extra wires are for hooking up the phasers or photon torpedo launchers. It was a very unusual accessory in 1965, but they are extremely handy for disposing of obstacles in your way! . . . .

So Im a little bit befuddled... Did the SBC come with a generator AND you used it? Or did you convert over to a Delcotron (internally regulated) alternator? I say Delcotron because it makes a one wire hook up sooo easy. Bill

Good question Bill! This actually confused me... The new harness came with the two prong plug, as used with alternators, so it plugged right in. I am running an alternator. Of course, it also uses the other red (hot?) wire as well.
Years ago, the generator finally burned out, and at that point a mechanic switched me over the alternator, and spliced the two prong plug in for me.
-
Im still confused... must be the someteimers LOL... I had a '62 impala with a 12V generator and my pals '63 had an alternator. That was the swap year for chevies. Now my '64 special came with a 37 amp 12V alternator (Its for sale BTW) with a firewall mounted regulator. I upgraded to the one wire system (as always!!) and now have a fool proof 100A 14.2 volt system.
Just an FYI... do your due diligence... with a genny putting out 20 amps downhill LOL, that HEI will suck up 12A, lights another 10-15A and a stereo, gosh be darned with an amp maybe another 10 amps. Heater fan is extra. Bill
-
It is an alternator. How many amps? No idea. Probably not many. You've got a point, and it might be why I've noticed the dome lights flicker a bit. Might be time to upgrade.
