i brought the innovate lm1 ed and instead of me buying the pricey rpm convertor or even the stupidly expensive auxbox i was trying to find a cheap why around them
getting round the auxbox is easy just need a mac 8 pin cable, cut one end off and wire it into 5v only signal wires
but the rpm is what i mainly want most of all, i was even thinking i could pick up a speedo of the signal wires behind the speedo but looking like im going to have to give in a by the rpm convertor
