I wired it just the way it sais. Still no luck.. Help

 

Did u put it in 4 cyl mode? What pin # and color of plug on the PCM did u tap into for the tach signal?

 

The Diagram features an old style MSD box, I have the new digital one. I called MSD and they sent me this diagram. They said the wireing is the same.

I put it on MODE 1 which is for LS1 induvidual coils ignition.

 

Isnt that diagram for an rpm activated switch, which has differnt wiring than the window switch? I am sure that there is at least one extra wire on the window switch that is used to close the circuit. I am in a similar situation, but havnt hooked up my window switch yet becuase I dont know how to. BTW, I have the switch which requires the pills so it too is may different than the digital.

 

nah, don't use mode one. It's a misprint I guess. LS1's put out a 4 cyl tach signal from the PCM to the tach guage. How exactly does it work, it just does. Like a posi-trak on a Plymouth. It just does! lol jk

 

so is my wireing correct?

 

Looks correct.

 

What about the wiring for a regular pill activated window switch? What are the differances, and how should I go about wiring mine up?


Thanks

I set it at cyl 4 and still nothing.

 

Uhm, one more quick ?. Do u have a NX or NOS kit. It's NOS in the pic but that doesn't mean u have one. I forget if the yellow is switched ground or power. You need to have the switched ground wire to trip your relay.

 

I thought the fuel switch was to be put in series with the window switch. Not in series with the solenoids?

 

The fuel switch can't handle the current of the solenoids. Put it inline with the window switch. In fact, the FPSS might be bad now.
