Does anyone know what the 2 pin sealed connectors Mercruiser uses on their wiring harnesses are?

[frostystorm]

The ones with the 2 pins, and rubber gaskets that clip together, I need to replace a single one and would really rather like to avoid splicing if at all possible, but will if I have to.

I have been looking for a source of them, but can't seem to find one.

Nailed it!

I was in the engine wiring section of marineengine/iboats and was only getting listings for full harnesses.

The 3.0 gets 20 amps of TKS voltage from it's own oil pressure switch, or it's 12v keyed, it's there regardless oil pressure would be ideal but keyed is good enough i don't turn the key on and leave it, so I got a 12v source with a clean connector right at the carb, and I am going to put in an electric choke carb, My TKS module works but the carb is all messed up internally due to a pasted hack job by someone else.

I got the stripped screws out but the kind of person who strips carb screws does other... things, half the carb is filled with RTV... etc.

I just can't bring myself to spend $1200 for a Rochester 2bbl, but want a clean install if I can muster it.

Turn-Key-Start: Theory of Operation:
3. On 3.0L engines, an oil pressure switchprovides a ground (-) path for the TKS module.
Positive (+) voltage is continuously supplied through a 20 amp fuse directly from the
engine circuit breaker.

How does TKS work (technically)?

Curious about the mechanics of the TKS system. There is no choke so how does that work? What causes the hissing sound it makes until things warm up? What are the mechanics of it all? Nothing is broken, just curious how it works from a technical perspective compared to a traditional carb.
