Wiring diagram/schematic of 67 442

Hi, I'm looking for a good wiring diagram for a 67 442. I've got a reproduction service manual but it's just black and white. I need color codes for wires to help chase things down.
Thanks
Dave

I know you hate to spring for another one but stuff like this is why I always recommend and encourage buying an original print copy of the factory service manuals over ANY reprint or digital copy.

With thousands of Oldsmobile dealers (who each had a herd of mechanics working for them, each of whom probably had his own copy) plus all the tech schools who purchased them, originals are still out there and usually affordable.

If you're really lucky you'll find one that the owner wrote a lot of notes, updates and timesavers in it.

Just think about the poor Chevrolet and Pontiac owners. All they ever had were black and white line drawing wiring diagrams. Probably why most of them have so much butchered cobbled up wiring.
What excuse do you have for all the Oldsmobile owners with cobbled up wires? The Chevy and other makes schematics list the color and size of the wires. Not real difficult to follow along.

I've replied to this at least 4 times and each time it fails. Hope it goes through this time.
I can't display the image, might be a VPN issue but all I get is blank discussion post. When I disable the VPN, it can't find the classicolds web site. Can you pm it to me?

Even Fords don't get subjected to it bad as those do. Having to repair electrical issues created by previous owners is a big reason I stay away from Chevrolets.

I can easily read b&w line wiring diagrams as I had to use them to troubleshoot and prepare lockout-tagout certificates at both fossil and nuclear powerplants. The Fisher Body manuals use those too. But Oldsmobile made things better with their color wiring diagrams.
I've got the privilege to own a Chevy that the original owner, my granddad, was a better engineer than me. The only changes he made look factory.

Comparatively speaking, it probably comes down to the amount of Oldsmobiles in population and the market segment that bought them vs Chevrolets and the other brands. Most Oldsmobile owners I knew growing up did not work on their own cars. Oldsmobile owners were older and more affluent than Chevy and Pontiac owners. Read through the Electrical forum and see how many Oldsmobiles are cobbled up over the years.

So does the OEM Oldsmobile Chassis Service Manual. As Glenn said, this is why you want to buy an ORIGINAL CSM and not a reprint or PDF.
