Hi everyone. I hope you are doing well.


I'm trying to purchase the PIVOT SPEED METER V (SML-V) for my car, which has the following specs:

Brand: Nissan
Model: Fairlady Z (JDM version)
Year: 2003
Chassis: z33
Transmission: Manual

And by looking at the compatibility chart, I found out that this product is indeed compatible with my car:



So then I go to the wiring speed signal chart, and I find out that I should follow the "N - d" diagram.


And this is the part where I get a little bit confused, because the "N - d" diagram shows a 4 pin connector.


And the problem with it is that I cannot find a 4 pin connector in my ECU in order to plug it in. Am I missing something?. Am I supposed to plug it in somewhere else?. If so, where can I find this 4 pin connector?.
Thanks a lot for your help and I really hope I can find a solution for this.

P.D.: I'm planning to do this, because I wanna take my car to a race track, and the top speed of JDM cars are always limited to 111 mph.
There aren't ECU tuners for this car where I currently live in, so reflashing my ECU isn't a valid option for me unfortunately.

Cheers.
