HELP - Aftermarket Tachometer Installation on b14

[alleykat2020]

I recently bought a 2" tachometer but not sure which colour wire on the distributer should be connected to the green signal wire on the tachometer. Can anyone help with this, or is there a better place to connect the signal wire. It is supposed to be connected to the negative terminal on the ignition coil, but I'm running a ga15de fuel injected, and i dont think it carries the traditional coil. Thanks for the help in advance.

it should be the green wire on the external distributor lead.
if you do not have one, an electricion needs to take it off of the black wire, leading to the internal coil in the distributor. be extremely careful with the second option, as shorting of those wire will have you looking for an external coil to be wired into (preferred), or a new distributor

it can be connected directly to the ECU using pin # 2

I have an SR20 with the external coil....which wire from the ecu is the tach signal to the tachometer?

it can be connected directly to the ECU using pin # 2

can anyone else confirm this??

um a miss type there bro it's pin # 3 if you want it wired yuh could check me .. on the ecu its the blue wire with a white stripe *note thats for the front wheel drive cars the 4WD colours are different well thats on ours when i wired the tacho it was the colour of the same colour used on pin # 2 of the FWD harness a Bit strange oh and the fellas who say that a tacho can't be wired to a QG without a tach adaptor um not true it could i did it the wire is there just as the GA has the connector close to the distributor there's one for the Qg there's another trick of finding the wire for any engine no matter the make . using a multimeter a good one though , i got a Fluke 179 put it on the AC scale and do a test . The Rpm wire will give a voltage of *app = 6V @ idle and as the RMP increase so will the voltage OR you could use the frequency scale too

[Anil_Sooknanan]

demented, the same goes for the SR

[katastrophic]

Anil_Sooknanan, my GA15 does not have the wire on the distributor....

[Anil_Sooknanan]

on the ecu its the blue wire with a white stripe

take it directly from the Ecu

[katastrophic]

Anil_Sooknanan, what about the O2 sensor... u kno where it is located on the ECU??

[katastrophic]

by chance u have an ecu pinout????

[Anil_Sooknanan]

yea but you could use the pin out from the SR it's the same for the basic stuff

^^^ok thanks...

I have a similar problem as the op, cud u identify which on of these wire is the tach signal?

use that
