I was doing some repair work on my engine harness before my new engine goes in and one connecter was in pretty poor shape and broke off right at the plug end. It was one of the 2 large wires in the harness with grey shielding on it. Anyone know what those 2 large ones go to? I dont have my engine here to check.

 

Sounds like the crank trigger to me....

 

replace the harness. i lost the engine in november due to an old harness.

 

The wires themselves are all in pretty decent shape, it was just the old tape and heat shrink stuff that was all brittle, once I re-wraped the whole thing it bends very easy and that was the only connecter that broke off. If I get approved for the mazda motorsports deal maybe i will buy a new one.
