TA22 taco not working

**JesseCrown** · 08-02-2006, 08:30 PM

hey guys
trying to get all the gauges working in my gf's celica
hard part is all the wiring is a complete mess, chances are that the taco gauge works fine its just a wire not connected or broken.
would anybody be able to tell me how to wire up the taco to where it goes, and what wires go where, i think its just a couple of body loom wires to coil isnt it?

thanks, jesse

A friend of mine has a pet rat she calls Taco.
I love (good) Mexican food.

Taco: A corn tortilla folded around a filling such as ground meat or cheese.

Anyway, the tacHo only needs a couple of wires: power, ground, and coil -ve. Make sure the tacho wire is connected to the coil -ve and isn't broken, fallen off, etc.

what motor/dizzy is it running, when i putt fuel injection on my 2tg for some reason the tacho was shorting the ECU.

its just a 2T with standard coil.

From memory it's a black wire around the coil for the tacho. That should be connected to the negative side of the coil.

i had the same problem with my 2tgeu is wasnt sparking coz the -ve coil wire must have shorted somewhere so took it off and it fired right up.

the wiring shouldnt be that much of a mess unless some one has been there. check connections on coil and the connections at the back of the cluster. tacho's wouldnt really play up i would think

Could still possibly be a faulty tacho, I had an RA40 which had a faulty tacho, replaced the unit with another and it worked fine. But for sure, check the wiring first.
