I posted this in the N2O forum as well, but nobody seems to know the answer.

Ok, I attempted to install my Jacobs Nitrous Mastermind today, and I know there's a couple people using them here. I bought it off e-bay, and it's never been used, but the instructions are a little vague and not very specific for wiring to an LT1. I have no idea what I did wrong, but I pretty much screwed it up. When I thought I was done, the car wouldn't start, and I have no use of the spray, neither solenoids are working. Those of you that have them, can you show me how you have everything wired up? A little about my system...I have a toggle in the ashtray, and a microswitch on the throttle body. I also have a Hobbs switch.

Right now, I have the red/white from the NMM going to the fuel sol. I have the blue from the NMM going to the N2O sol. I have the white from the NMM going to the wire from my toggle. The brown wire from the NMM is going to the Hobbs, and the Hobbs is grounded at a known good ground. The other two leads from my sols are going to the throttle body switch. What did I do wrong?

Now for the ignition part of it...I have the Accel 300+ ignition. I found what I thought to be the signal input wire to the 300+ (white wire). I cut it, and on the coil side I spliced the green wire, and on the other side I spliced the yellow. The car wouldn't start. I cut the wires and put the white back together, and the car starts. Obviosly, I had the wrong wire, or did soething wrong. I was told it was a white wire to cut into though. Can anybody give me a hand? Thanks.


EDIT- BTW, my unit powers up ok, and the "nitrous armed" light comes on with the toggle, but no "nitrous flowing" light when full throttle.

I was thinking about it, and I may have wired the solenoids properly. They won't activate unless there is an input from the ignition lead. So, I need to get the ignition figured out before I even know if the solenoids are wired right.
