Default any mk4 escort rev counters use a negative pulse?

i went to connect my omex up to my s2 and the omex has a negative pulse but the rev counter needs a live

i know my s2 dials need a live pulse because i flicked a bit of wire conected to the green cable on the multiplug over a live and the needle moved up slightly but the omex 500 uses an earthed pulse to make the dials work

so are there any rev counters out there that will work with a negative pulse?

cheers! mr v

i thought they all used nagative pulses, cos it takes the feed from the -ve on the coil?

think you will find if you have a coilpack, it wont read properly though... afaik, a resistor helps with this though
