None of this is even remotely close to what I am seeing on my PCM....
I have a gray connector and a black connector on the PCM.. which one is X1 and Which one is X2?

I know this is an old post but wanted to clear up a few things.

***Pin #20 is a fuel injector wire and should not be used.***
(It MAY cause intermittent flashing due to the fuel injector erratic signal. )

The tried and true method is to use any coil signal (we recommend pin #75 on the X2 (gray connector) for the rpm signal). This is a dark green wire in this position.

We also recommend pin #71 on the X1 Connector (black connector) for the Vehicle Speed Signal (Vss). This is a gray wire with black stripe.

The dual mode has the ability to set for high sensitivity sensing since the signal is weak from the PCM.

The single mode has to be programmed before shipping for high sensitivity mode since there are no buttons to change it once a customer gets it.

PCM located on passenger side in engine bay.

"X1" (black) is toward the front of the vehicle on the PCM.
"X2" (gray) is toward the rear of the vehicle on the PCM.
You can only see the colors (blk and gray) once the connectors are disconnected.


Not trying to spam, just wanted to get the correct info out there.
