Wire Harnesses for 1972 Mercury 402E

[carsonmurph1]

I recently bought a 1972 Crestliner Stinger 14' with '72 Mercury 402E Outboard. I have a couple different posts in the restoration and control forums, as well. As far as this post goes, I'm rewiring the entire engine. All the wiring was dry rotted, and while it all seemed to work, I didn't feel comfortable going out on the water with wiring as frayed as this was.
I found the wiring diagram, and I had some wiring equipment in my basement, so I took care of the coils and ground wiring. I'm trying to find both the engine side and boat side wire harnesses where the main electrical cables plug into the side of the outboard. I have found both parts online, but they're very expensive. Does anybody have any ideas for an alternative that may be a little cheaper? Here is what I have found so far:

Engine Side Harness from CDI Electronics, Part no. 414-2770. https://www.amazon.com/CDI-Electronics-4142770-MERCURY-HARNESS/dp/B007I8WE60

Boat Side Harness also from CDI Electronics, Part no. 474-9550. https://www.amazon.com/CDI-Electron...HCFXKCBJB3H&psc=1&refRID=XASYKB3C7HCFXKCBJB3H

Thanks for your help!

Those are some pretty " reasonable " prices considering they replace a NLA obsolete for a 50 year old motor.
CDI makes good stuff, and they are a lot cheaper than what Mercury offered just a few years ago.

I would look around some more for the engine harness. When I needed one for my '77 Merc, there were plenty of sites and prices to choose from. It was about $100.

The boat harness may be harder to find. You could make one up pretty easy, if you still have the old Quick-disconnect plug and it is serviceable. You would butt joint, solder and shrink tube the new wire to the quick disconnect plug and solder the other ends to the MerControl.

You would need about 20' each of wire colored red, black, yellow, brown, grey and orange or white, plus some of that split plastic casing (or electrical tape) to hold it together.
