Just go to GMPerformance parts and order the new kit part#19260247. It is a new timing cover with sensors and openings for both the crankshaft sensor -58X and camshaft sensor 4X, the timing gears and chain set and a crankshaft mounted reluctor fror the crankshaft sensor. All in a nice package that is a bolt on, keeps reluctor and sensors inside the engine and out of salt water or such. It's also very reasonably priced. This is the same setup Mercury Racing uses on the new HP525efi and HP565efi engines.

I'm told the computer needs reworked if you go that route. different number of teeth on crank trigger wheel from outside of engine to inside. and unsure of number of targets for cam sensor when used that way. just what I'm told anyway. thanks, Tom

Anyone used the GM crank trigger kits with a 525 gen 2? I have a gen 2 wiring harness and looking to use the GM kit and the Mercury reluctor to make it work. Is there any computer differences between the different generations due to the crank and cam position sensor location changes?

Has anyone adapted a gen 2 wiring harness to work on a gen 1 525. The plug ins for the sensors are different I can see and obviously wire length. Wondering if I can change connectors and it will work correctly or just convert the motor to later style with the crank and cam sensors in the timing chain cover.
