Crank trigger problem

Postby kevdachev on Thu Jul 03, 2025 4:52 am

Hi i have a M800 ecu which l use for my SBC drag truck. I have recently changed the engine for a GM LS engine. On the original SBC I used a MSD crank trigger system with four rotating magnets on the front pulley. This had a 2 pin connector plug (orange and blue wires) Now on the LS I have the 24x black sensor which is 3 pin. How to I wire the new sensor to work with the M800 system please.
Thanks Kev

Hi Kev,

The attached files should be able to assist in the wiring and setup of this sensor.
