ok looks simple enough so do I have to replace an existing resistor with a r30 one or add one to the board thanks for your help

remove existing and replace it with something from 18 to 27k google vems schematics, you will find where it's located

located it on the schematics does this look like the corect replacement resistor

looks like right one

right ive replaced the resistor and left sj2 unsoldered and soldered sj6 only problem is getting no rev counter  and no trigger is there anyway o test if the ecu is reeding the trigger ive scoped the crank sensor and working fine
