How To: C15a Wire-3 restoration

[Jordan Baker]

Started installing the front harness today. It was quite the job getting the dash wires to feed through the hole. Eventually everything got pushed and pulled through. I also started securing the harness to the cab frame with some clips. I’m so glad I went the extra and put the metal shielding on everything. It looks just like how the original should.

In my last photo showing the various holes. What are they all for? I know the top one is for the main wiring harness. Does anyone have any documents on what goes where?

The oval hole gets a rubber grommet with 4 holes in it that cushions the temperature line, choke cable, throttle cable and oil pressure line. the two smaller round holes above and below the oval are for bolts securing the tin that holds the grommet.
One vendor is Steele Rubber https://www.steelerubber.com/firewal...met-60-0010-45 Other vendors sell it too, Steele just had a clearer photo than Chevs of the 40s....

Thanks Grant. I should have said that I have the rubber bushing. Any idea on the other two larger holes? I’m guessing the speedometer cable goes in one of them.

Jordan.

Would the vacuume lines for the wipers occupy one of them?

Hi Jordan

Your truck has one more hole comin in from the engine compartment than I've seen before, wonder if it was drilled to replace a wire or possibly for a replacement temperature gauge tube.

Here is same area on my HUP

As you have discovered the only practical way to work on the dash and engine compartment wiring is with nose off. I make this comment to anyone planning to replace or do major work on the wiring in this area.

Jordan though I'll guess you have looked at the section on wiring on my web page, here is the link for people getting into wiring on thier CMPs http://canadianmilitarypattern.com/C...formatioSn.htm I've included the link instead of posting over all the photos because you can punch down to much higher resolution than is practical on MLU.

Cheers Phil

PS In response to Davids comment on vacuum line, the vacuum line for the wipers on mine goes up through the center post on the windshield.

Hi David.

As Phil says the vacuum line goes up through the top between the main windshield frame.

Phil, yes I have been checking out your photos from your website quite a bit the past few days.
