Sun Tac. not working

[The purple one]

I just put a used tac. in my 93. Hooked up to the tan wire with the yellow line (I did this in the engine comp. not under the dash.) But it no work Is there a way to test the tac. or am I doing somthing else wrong? One more thing I did not hook up the back light for the tac. Do not know if this would make any differance. Also I have a good ground and a good power supply.

what did you hook up the signal wire to? my sun has a green wire for the signal and a blue wire for the backlight.

the signal wire goes to the ignition coil ground

Is the ignition coil ground the tan with yellow strip? That is what I hooked the green wire too.

i've heard its the tan wire but im not sure. is this a 4 cylinder? if so hook it to the exhaust side coil

 

[The purple one]

It is a 4cyl. What color wire on that side? Thanks

For 1993 & 1994, Depending on the size of the motor, you can do the following:

2.3L - Off the PCM (powertrain control module) go to pin 4, which is a tan wire with a yellow stripe. Or, go to the ICM (ignition control module) and splice pin 12, which is a tan wire w/yellow stripe - this is the same for the 4.0L, too, except for the ICM connection, it will be pin 2 instead of 12.
