HI Richard,

Was tidying up my install lately and removed the 12v +ve red lead from the yellow connector to the +ve of one of the injectors. Recently I have been getting misfire on cyl 5&7 when the system is active - could the HFS be interfering with ignition / ecu?

I know there is an alternative location for the +ve red cable (yellow connector) to a red and blue wire - but I cannot locate it!!!

Can I connect the red (Yellow connector) wire to a manully switched 12v source? What does this +ve do that does not allow it to be switched to the 12v acc on switch?

Any help appreciated?

Regards
