Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
If you are trying to tap into the car to capture the vehicle speed, that is next to impossible now. These cars use all 4 ABS sensors to determine vehicle speed. That signal goes to the transmission and cluster that that info it then shared to the Ecm from that point. So there is no speed sensor.
The only way to accomplish this is if the Taximeter you have has some sort of sub harness to plug into the meter to capture and share the signal.
I would need to spend some time reviewing this info after work to see what can be done to install it. Can you wait till later this evening?
That wiring diagram is horrible!!! I can't make anything out of that. I would recommend you don't mess with it and have it installed by a installer that has done it. Other wise you can damage control units if not hooked up properly.
