Hello? Any suggestions?
Customer: replied 7 months ago.
The original sensor didnt have a plug, just the 2 wires pushed into the pins. I'm wondering if the wires are crossed, will this make a difference?
Customer: replied 7 months ago.
Hello?????
Expert:  Richard replied 7 months ago.
The original sensor has a all pigtail wire on it so that is how the new one should have come. If it is an aftermarket part then yes the wires can be crossed.
Customer: replied 7 months ago.
We tried crossing the wires the opposite way, but it did not even start. Back to original position now and we have had the minus side off the battery for a half hour

Ok, with the new sensor and the wires are correct, reset the inertia switch and unplugged the battery, we still get the four codes. What do you suggest we do next?

Until you actually help us and solve the problem, we cannot rate you. So far you have only asked questions and not given us answers. We still need to have the car working. I feel tricked out of hard earned money.
