Alrite guys, i got a question, i just got a tach which came off of a 92 civic gauge cluster. i wanna hook it up to my car (91 DX Hatch)(no tach ) but yea it seems pretty easy, had a connection for GND, ING, and PLS (which i dont know what it means) how would i hook this all up? now the GND is easy, but whats PLS? and for the ignition, would that be to the actual coil or ignition as when u turn the key on?
TIA

 

NM guys i think i got it.
gonna take some experimenting.
blue wire from distr, gnd and ignition to pos
thanks anyways

 

did you every figure out how to put the tach into your dx? i have the same problem going on in my 91. Plese let me know
