Wiring MSD 8680 timing retard for activation with n2o only.
I've looked through all the diagrams in the stickies and searched with no luck.
Just finished installing a TNT plate kit on a 97 formula but I'm having trouble with the timing retard. Right now, I have the msd retard hooked up to only be powered up when the n2o arming switch is turned on. So the red is going to my arming relay and the black to chassis ground. The yellow wire from the retard is hooked to the white wire from the MSD 6AL, and the white wire from the retard is going to the white on the MSD harness which goes over to the coil. So the retard box is basically placed inline between the 6AL and the coil. The problem I'm having is that the car does not want to run unless I have the arming switch turned on (retard turned on). Would I be correct to say that when the retard is not powered on that it does not pass the signal coming through the white and yellow wires? I only want the retard to be activate when I'm spraying. If the arming switch is off (retard turned off) the car idles very low, pops, etc. I know the 6AL is fine as I can bypass the retard and it works fine.
