I have my tnt kit wired up and it doe's not fire the noids!!! Here is how I have it wired.......Switch(arm) wire to WOT switch then to msd window switch red wire then yellow wire from msd to relay #86 slot....Is this wrong?? Do I take the yellow wire on the msd and send it to the #85 slot(ground spot) on the relay...If so do I then just wire the red wire from the msd to the battery??? I hope someone can help me out!!!!

Please double check as i haven't looked at the wiring in a while but i believe the pulsed ground wire is the one that should be hooked up to the relay. The relay will have a power wire connected to it but the pulsed ground from the msd unit signaling the proper window will send the ground charge which activates the relay, sending direct current to the solenoids.

also if your using a Hobbs switch in line with the Fuel make sure it is bypassed for testing..

you want your red to the window switch direct to either A, +12 ignition, or B +12 ARM
(blue wire coming from your harness) , you need to have the MSD powered up regardless of the WOT position.

you connect the yellow wire to the ground spot of the RELAY and connect the other side to the ARM switch, install the FPSS and WOT switches between this wire. you can put them on the ground side of the relay if you want. But i like to put everything on the +12 side, and send the relay direct to the MSD switch.

ARM(blue wire)--T-------*WOT*--------*FPSS*----RELAY----*----MSD yellow.
--------Red wire MSD--------------------------------
Good luck, and if you need any help, feel free to PM me.

I can scan a wiring diagram in if you need it.

I tryed to rewire it today and got nothing..Then I bypassed the window switch and boom they fire!!!!!!Maybe there is something wrong with my window switch.....And yes I did cut the loops......

The MSD window switch red wire should go to 12v +
White to tach output
black to ground

yellow should go to GRD side of FPSS if you have it. The GRD wire from relay should go to other side of FPSS.

If no FPSS the yellow from MSD window switch should go to the ground wire of relay. This is white on my relay.

that make sense?

IntenseSS

I tried this....Red to 12+ then black to ground then yellow to ground on relay than....The window switch is controling the ground on the relay...But it stll did not fire...I will try one more time and get back to you guys thanks

You can take a wire and connect the two sides of the on side of the window switch right....This way I don't have to rev the motor to 3000 rpm...It should actvate it if all is wired correct....Right?????

I don't know for sure. I would imagine the RPM pills are resistors. I'd just rev it to 3k to verify.

If u can do that it would be awesome I wanna see it.

IntenseSS

I got it working Thanks all you guys for your help!!!!! Believe it or not my car is so loud that When I was in the front of the car reving the motor and hitting the throttle switch a was never getting to 3000 rpms....Here I was thinking I was redlining the car but I was'nt...Should of just had some one look for me.....
