    Im currently using a AutoMeter shift light with a mag signal converter but sometimes get a false sift light.
    Is there a better way? Any suggestion or advice would be appreciated. Thanks.

    I have the same issue. I cant even get a tach signal. I have routed my wires several different ways, made sure everything was grounded, tried and RF signal reducer and lastly switched to suppression wires and still nothing. I am very curious for answers as well.

    shift light

    Lahey's has a digital switch, 6-8 dip switches to set rpm, works great on NFC with Mallory, nothing else would work

    We have never had any luck using an auto meter tach with a mag. Ours lasted about 30 seconds then it stuck at 9500, didn't return to zero until the old man threw it across the shop. We went to a stack tach. Spectacular piece. Shock mounted, impervious to all the interference off the mag. Great product.

    look under products, it's the 95.00 RPM switch, but you will need other stuff so call for details
