Off the top of my head I don't know but here are some manuals I found for you on eBay starting at $30. Might be a good idea to get one as part numbers and manuals are just going to get harder and harder to find as time goes on.

Ayuh,.... AC Delco, MR43T....

An automotive set of wires will be too short, 'n have the wrong ends on 'em, so either build yer own, or buy the Proper set...

Get a kit and build your own. It is a very easy job and you know they will be right.

My Files Not sure what year manual this is, but it is a factory OMC FSM. I use it all the time. The only error I have found in it is related to wiring up an alternator.
