Toyota EP91 wiring


Recommended Posts

Hi, I was wondering if anyone would be able to help me wire up my g4+ atom to my Toyota Glanza Ep91. 


I will be running a external map sensor through the standard wiring. 

I have a button on the dash that goes to pin 20 (bc) on connector 1 that I'd like to keep. 

If I could get something like this it would be grea. 

I will also be using my innovate wideband as a input instead of the stock lambda sensor.

Hi Karl,

Have a go at lining up the inputs and outputs and then post the results back up here, we will be happy to offer feedback on what needs changing.

You might end up with something like this:



I did notice that the injectors are in two pairs, you may like to consider running two extra wires from ECU to injectors so you can do sequential injection.

Hi Scott,


Thanks very much for your reply. I will look into that and get that written out this evening.

Also am I right in thinking I cant use AUX 5 and AUX 6 on the atom? Are these used for CAN on the atom?

Its just that the the manual suggests using AUX 5 and higher for PWM or can I use any AUX pin?
