help!! with a vr4 tacho interface on a 4agze

[1598cc]

firstly, what do they look like.. i have what i think is one, looks very similar to a TPS (throttle position sensor) xcept without the turny bit on one side.


also, how is the wiring connected? ( its got a 4 prong plug female so im guessing i have to make a one up to plug into it?)

basically im setting up extra injectors and need a RPM feed.. was thinking of taking it straight off the ecu but ive heard its to weak to use ??



cheers

it has tacho interface written on the top face of it.
wiring wise- these are also labelled(in, in, out) the out terminal connects to your tacho gauge and the in terminals(2 of them) connect to each of the signal wires on the coils.

If anyone is after these i have 3 left in stock @ $30 a pop

im confused, wot do these do? is it for runing a tacho of a twin coil setup i.e rotary, coil pack? how would u setup an extra injector with this?

when u buy an extra injector controller, it needs a signal to control it.

i c, so ur not actually using the interface to run the extra injector, ur using an extra injector controller with the signal from the interface coooooool
