    Mercury tps

    Hello guys. I've got a 1999 225 efi with a dead tps. Mercury #821664. I am making my own pig tail to set it I just need to know the correct volts and wire colors to set it up right. I have a 3 wire tps but I think I will only need the ground a 1 other wire from the harness. Any help will be appreciated. Thanks

    .95 +/- .05 VDC.

    Normally aim for .96-.98 VDC (at idle).
