Hi! my name is Solomon Kim. Im new here and i needed alot of help!

I drive a 1989 Nissan 240sx coupe W/SR20DET. Im trying to wire up a kill switch to my ECU for theif preventions but
I dont know which to wire to cut and put a on and off switch between it. Just wondering which one did most of you guys used?
What wires did u guys use?
How many amp on the switch?
Did u guys have to use a relay?

Thanks you guys

why are you trying to put a kill switch on the ecu, why not just do a starter kill or ignition kill? Very east to do both just need a relay and switch. If you want I can tell you how to wire it, just PM me. Good luck

just pull the fuel pump fuse

I would think it would be risky to wire up anything to the ecu unless it was meant for it.

that would reset the ecu everytime too...

fuel pump makes more sense

why would you want to cut the ecu. if you put the cut off on the ignition system and the fuel pump then the car is going nowhere
