Raptor Dual Mode shift light
 

Thanks,

Will put info to work on Black Raptor Dual Mode install when recieved....ordered yesterday :thumbup:

-engine speed at X2 pin 75 (dark green wire)
(set to 1 cylinder mode)

-vehicle speed signal at X1, Pin 71, Gray wire with black stripe

-more info here http://www.raptorperformance.com/pag...install-camaro

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?

For those still trying to figure out the Pins..
I spoke with Raptor Performance VIa Email, and this is some added info they sent me.
Here you go.

Here is a complete DIY for the Raptor Shift light

.

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.
Our website has pictures and detailed info for reference.

So on the X1 plug, which number wire is for the 02 sensor signal wire? and is for left or right?

And on the X2 plug, which one is the signal wire for the O2 sensor on that one, and is the left or right?

I am trying to hook up narrow band gauges to monitor exhaust AFR's for a shot of juice. It would be easier for me to use the narrow band gauges I already have. I need to wire a positive and negative connection to the fuse box area and if I could find the signal wires for the O2 sensors for each side, I would be set.

Thanks in advance.....

60 0.5 TN 1667 HO2S Low Signal Bank 2 Sensor 1

Yes thank you, but which one do I use for the main signal wire on each side? (I only need one per side, one for each gauge).

I have no clue. I just copied the stuff from the service manual. If it were me, I'd use a wideband. I am sure someone out there knows how to do it. Have you checked over on LS1 te ch to see how people have done it with a narrow band?

I just did a quick search and read a narrow band will only tell you whether you are lean, rich, or at stoich. A wideband will give you numbers to work with. Based on that, I'd definitely go wideband. A wideband is cheaper than a new engine. Also, with a wideband, you can further use it to shut the n2o down if the reading go outside parameters you set.
