Need Mercuiser wiring diagram, pictures or tutorial for 1997 4.3 vortec

[oregonrafter]

I bought a 1997 4.3 mercruiser engine that had the wiring harness removed. I purchased a wiring harness, and now I need to install it. Do you know of a source for pictures or a diagram for this?
Your help is greatly appreciated.
...It's sort of intimidating looking at a big ball of spaghetti wires. I found that drinking a beer and staring at it didn't help near as much as I thought it would.

Here is a link to the electrical section of your Mercruiser's service manu@l. By using the buttons below it you can find the wiring diagrams you are looking for along with the rest of the service manu@l:

Boatinfo - Mercruiser Service Manual nr. 18 - 1993-1997 - Engines GM V6 Gen II Balance Shaft


Here is the very beginning of the manual:

Boatinfo - Mercruiser Service Manual nr. 18 - 1993-1997 - Engines GM V6 Gen II Balance Shaft

or go here and enter your serial # then on the right hand side of the page select "electrical diagram" from the very bottom of your drop down menu.

Thanks, tazrig. The Boatinfo site has the wiring diagram, but the resolution is so poor that I can't see enough of the details to know what colors the wires should be. The Brunswick.com diagrams are good, but these are parts diagrams only, and don't show where each wire terminates.

I was able to find an entire service manual online, after extensive searching. I've downloaded it and saved it for future nightmares. ;-)

You may want to drink several during installation. Let me know if you need pics of wire routing.

Care to share where you found the files at? Kind of having the same issues.

Be really careful guys. Hackers are able to put bad software inside pdf’s now.
