Default ms2 and 1.6 fuel pump

Can I swap out the stock fuel pump circuit triggering relay for another one and use 4 pins to just have MS trigger the fuel pump?

do you have the DIYPNP? i cant remember? you can build a simple high side driver circuit and do what the MSPNP does.

On a couple of installs, the high side driver on the DIYPNP didn't work for me, I don't know why. I always use two NPN transistors to invert the signal and provide the 12V to the relay.

I build this circuit. Requires removal of ST SIG fuse.



(it's the same circuit as used for VTEC)
