2007 Mercruiser 4.3 wiring harness plug

[Gallen47]

Can some one help me with a diagram?
The old plug ins had numbers and this one has letters and are much smaller. I am trying to bench start the engine I just rebuilt.
The old style you could ground 5&6 and add 12 volts to 7 to start the engine, what are the 2 letters that need grounded on the new one?


Thanks!

I'm thinking your talking about the 14 pin connector instead of the 10 pin. Suggest posting a pic to verify

Yes it is a 14 pin connector, the pins are designated by letter instead of number?

Pretty sure you're not going to find a wiring diagram online for this as Mercruiser went to something different for wiring diagrams right around 2007....Edit : I take that back, It seems the diagram might be in here, http://calabriaboats.com/merc_service_manual/90-863758070_9A.pdf

About the best I can quickly locate would be this which you might be able to use as a pattern since it has the numbers and not letters......Just be careful...If you don't like this idea I believe they have a remote starter with this design harness.

Here you go,
A - 12V
B - Ground
C - Wake (ignition ON)
N - Crank (Start)



They also make a 10 to 14 pin connector so you can do it the old way

I am still have problems with the wiring harness, the 15 amp fuse that is just behind the main harness plugg keeps blowing and then the engine will not crank? Any ideas?


Thanks!

I hope your not try to ground two pins, you don't ground pins even with the 10 pin. Jump A to C, then Temp jump A to N to start. Only ground would be pin B

Sorry I did not make myself clear. I have dropped the engine in the boat and connected everything. It cranks from the key but does not fire. If I continue to crank it blows the 15 amp fuse that is first from the main plug that plugs into the wiring harness on the boat. Where can I get info on the fuses that are on the harness?

Thanks

Guess I need to know which 15 amp fuse it is. If your talking about the ignition fuse I'm seeing it should be a 20 amp
