im going to be installing my msd 2 step today. According to the instructions with a manual I should use only the white/blue activation wire and splice it to the clutch switch wire (12 volts)...which wire is that? according to a wiring diagram I have, the clutch switch connector is a 4 wire. (brown/white, pink, gray, black/white)

the brown/white is cpp switch signal
the pink is ignition 1 voltage
the gray is cpp switch signal
the black is ground

so I'm guessing either the brown/white wire or gray???
where is everyone hooking theirs to that have a manual??

Looks like it's a 2 wire connector. Purple/White is the Supply Voltage. Dark Green is the Signal

 

hmmmI just found that diagram you're referring to in all data...i didnt see that one at first...i'll show ya what I found at first...



So if you're correct and i am as well...I should tap into the dark green wire that you are referring to and ignore the diagram I found???

 

actually Shouldn't I splice in at the ppl/wht wire? Cause the DK GRN is hot at all times right?

Where is the clutch pedal start switch connector at? Is it by the clutch pedal???

 

That's from GM's Service Information. It says Clutch Pedal Position Circuit, then when you click the link it takes you to Clutch Pedal Start Switch.

You would want to splice into the Dark Green Wire. The Purple/White is constant 12v.

The sensor in underneath the dash, where the pedal is.

 

Sweet...Thanks!!!

 

Good luck, let us know how it goes.

 

I got everything working. In the end the wire that needs to be used is the gray wire that is on the 4 wire harness. when the clutch is pressed in, it is 12V. (clutch pedal position switch) The two pin connector is only for start up and only sends voltage when the key is turned all the way in the ignition (starting)

 

so how is it set up with your 6 speed? i'm about to buy one for mine

 

i got tired of trying to figure out which wire on the upper clutch switch so i jumped the lower clutch safety switch harness and ran a wire to a ground from one side of the switch and the trigger to the ground input on the other side of the switch

works great, although now i can start the car without pushing the clutch in

other that figuring out which wire to tap in to, install takes ten minutes

 

10 min job how did you get the signal wire through the firewall? or any of you that is my main problem.

 

There's a grommet on the passenger side under the PCM.

 

ooo thank you, i know some ppl that drill holes to run the wire. i knew there had to be a acces hole

 

Remember, no matter what.....there is ALWAYS an acces hole

 

no doubt there is always a hole to snake around in.

 

I hooked into the wires by the blue pcm cable pin 32 .its a grey wire, works perfect when clutch is pushed in.
