tach signal location for window switch on tpi
as title says, i want to hook my nitrous kit up to my 91 and i was wondering if the tach signal is just off the coil or if its a seperate wire of the computer? and would anyone happen to have pictures to which wire it is? thanks for the help

I'm about 90% sure that either white wire off the ignition coil is what you want (I would use the one that does not go back into the distributor). Don't be fooled by the two two wire connectors, as it is still your standard ignition coil with a constant 12V and triggered by grounding the negative side.
